Title: My Custom Case Build Post by: CartmanSPC on July 21, 2013, 09:15:20 AM In the process of building a custom case for my mining rig. Thought others may find it interesting to see the progress.
It will be going into a 19" rack so the dimensions were made to fit. Dimensions Length 600mm Width 446mm Height 221mm (5U) What I have built so far https://i.imgur.com/8xZwEZuh.jpg https://i.imgur.com/G6FzCfFh.jpg Using rivets to hold the pieces together https://i.imgur.com/OluLnbDh.jpg https://i.imgur.com/KkUiDyDh.jpg Made one of the holes too close to the others so the rivet wouldn't fit :/ Luckily I had enough room to drill another hole. Lesson learned. https://i.imgur.com/ja4Wanbh.jpg https://i.imgur.com/s4TtWPqh.jpg Will update my progress as I get further into it. Title: Re: My Custom Case Build Post by: notlist3d on July 21, 2013, 09:35:33 AM Looks very nice and clean so far.

Title: Re: My Custom Case Build Post by: CartmanSPC on July 23, 2013, 07:53:40 AM :D Thanks!
This is really turning into a labor of love. It doesn't help that I am a perfectionist when it comes to this type of stuff :-\ Trying not to let that extra hole drive me nuts ::) Slowly making progress. https://i.imgur.com/69TTloNh.jpg This is what the GPU holder will look like. Going to fasten it down somehow. Perhaps with some kind of quick release clamps on either side. Measured that there is room for 23-24 slots. That will allow me to have a bit more than one slot of room between cards (7 is the goal). https://i.imgur.com/XqZAarLh.jpg Title: Re: My Custom Case Build Post by: borgfish on July 23, 2013, 02:36:28 PM i see you already used like 24 rivet's, keep us updated any time you use another one
seriously, it's gotta have taken you more time to upload those pics than asselmbe this 12 pieces ?? guess we have a summer hole in news here Title: Re: My Custom Case Build Post by: CartmanSPC on July 24, 2013, 09:06:17 AM Title: Re: My Custom Case Build Post by: flipper on July 26, 2013, 05:37:25 AM I'm impressed at the quality, so far. Want to see more.
Title: Re: My Custom Case Build Post by: mazedk on July 26, 2013, 05:58:52 AM Looks very nice.
Why did you make it 5U though? - From my experience you can go 4U and still move quite a big amount of air with the right fans (which you could do seeing as you are hosting it in an rack/server room im guessing?) Title: Re: My Custom Case Build Post by: peonminer on July 26, 2013, 06:08:35 PM oh man looking good! Can't wait to see the finished product. Love the airflow.
Title: Re: My Custom Case Build Post by: The Goat Master on July 27, 2013, 01:50:05 AM Where did you get the parts? It looks really nice!
Title: Re: My Custom Case Build Post by: CartmanSPC on July 27, 2013, 04:01:50 AM Why did you make it 5U though? - From my experience you can go 4U and still move quite a big amount of air with the right fans (which you could do seeing as you are hosting it in an rack/server room im guessing?) I initially wanted to make it 4U but after measuring I felt it was a bit cramped. I may enclose the case to build a wind tunnel type enclosure if the temperature on the cards are too high with the stock fans. The power supply's will be in the front half of the case so I also wanted to have some space for more air to flow in. I can fit 8 5U cases in a 42U rack vs 10 4U cases. The power requirements to support 8 cases may already be higher than can be provided as the environment has strict watts per square foot restrictions. I currently have one 20amp PDU to power the rig and I know I can get at least 30amp PDUs when the time comes but don't know if I can get anything higher. By that point I may need to acquire more floor space to accommodate the watts. I will have a better idea how many amps/watts each rig will draw after I get the first one going. Basically my thinking was that case space was not an issue and I wanted to error on the safe side. If/when I build a second one I will have more experience to see if a 4U case will work. I will also be purchasing a nice mider saw if I build anymore as cutting the aluminum with a hacksaw and then smoothing out the edges with a dremel took a lot of time and effort! Title: Re: My Custom Case Build Post by: CartmanSPC on July 27, 2013, 04:21:21 AM Where did you get the parts? It looks really nice! I initially looked at using 80/20 for the case but found it to be too expensive. Consisting of 1" square extrusions I also think 80/20 takes up too much valuable space on the interior of the case. Trying to fit 7 GPUs in the width of 442mm is going to be hard enough without also loosing 2" for the side walls. The way it is now I have 442mm of space for GPUs. 4mm for the aluminum sides (2mm each side) and then another 2mm for the side panels (if I decide to use them) for a total of 448mm. Looking at how it turned out I think I could of increased the interior to 444mm and put the sides on within the space between the long aluminum pieces. This is a learning process for me so I'm finding what works along the way :) I think these are the two size angle bars I am using: http://www.homedepot.com/p/Crown-Bolt-1-2-in-x-96-in-Aluminum-Angle-Bar-with-1-20-in-Thick-56780/202183473#.UfNGEiTn-M8 http://www.homedepot.com/p/3-4-in-x-96-in-x-0-050-in-Aluminum-Thick-Angle-56930/100337439#.UfNGDCTn-M8 Larger pieces for the exterior frame. Smaller ones will be used for the interior GPU stand. Title: Re: My Custom Case Build Post by: CartmanSPC on July 29, 2013, 08:37:51 AM Here are the aluminum part used:
https://i.imgur.com/5wk73kN.jpg ...and one more for the Power Supply section: https://i.imgur.com/aXLq1MAh.jpg Worked on the motherboard section tonight. Screwing in the MB standoffs worked better than expected. https://i.imgur.com/AbtzMsL.jpg Really had a hard time drilling the holes since the top part of the frame interfered with the drill. In hindsight I should have turned it upside down and drilled from the bottom :/ https://i.imgur.com/TkjcaSB.jpg Test for fit.

Title: Re: My Custom Case Build Post by: networkgeek24 on July 31, 2013, 03:04:49 AM How do you plan on attaching this case to the rack? Very interested in this as I have an old unused server room with many 4 post racks that I'm eyeballing for a similar build.
Title: Re: My Custom Case Build Post by: locke9342 on July 31, 2013, 05:15:55 PM That looks really good. Wish I could make stuff like that.
Title: Re: My Custom Case Build Post by: CartmanSPC on July 31, 2013, 07:18:05 PM How do you plan on attaching this case to the rack? Very interested in this as I have an old unused server room with many 4 post racks that I'm eyeballing for a similar build. For this first one I will use my existing rack shelves. In the future I plan to use something like this: http://www.racksolutions.com/media/catalog/product/cache/16/image/5e06319eda06f020e43594a9c230972d/t/o/tool-less-rack-rail-1u-500w_2.gif http://www.racksolutions.com/tool-less-rack-rails.html Title: Re: My Custom Case Build Post by: Dougie on July 31, 2013, 07:28:52 PM Is it your basement that you're building this? What are the cages for? Sorry. I'm just nosey. Interesting thread.

Gives you a bit more airflow around the underside of the motherboard aswell. How are you planning fans to be mounted? Any updated pictures? Title: Re: My Custom Case Build Post by: Dougie on August 01, 2013, 09:34:39 AM :) Thanks! Looks like a good place for building stuff. Good luck.

Title: Re: My Custom Case Build Post by: CartmanSPC on August 05, 2013, 08:25:47 AM Big update. Case is done!
Now I am in the process of mounting the components...

Will run it as is without GPUs to get a baseline of power usage. Hope to get the GPUs installed in the next few days as time permits :/ Title: Re: My Custom Case Build Post by: Dougie on August 05, 2013, 02:52:26 PM It looks really nice and clean. How many GPUs are you going to install?
Would you mind updating with total cost of the rig and case once you're done?! Thanks. Title: Re: My Custom Case Build Post by: networkgeek24 on August 05, 2013, 08:37:50 PM Any plans to make this hold two motherboards and double the GPU's in the future? It would get a little tight, but I think it would fit.

Title: Re: My Custom Case Build Post by: CartmanSPC on August 08, 2013, 05:35:54 PM First GPU installed. Starting to rethink running 7 GPUs with two 1200 watt power supply's from a cost perspective.
https://i.imgur.com/sdB4pbZ.jpg https://i.imgur.com/bE9ZfTU.jpg Title: Re: My Custom Case Build Post by: CartmanSPC on August 08, 2013, 06:14:46 PM Thinking about the cost of a 7 GPU system vs a 5 GPU system.
Everything else being equal: 7 GPU system Power Supply 2x$285.15 $570.30 GPU 7x$377.36 $2,641.52 Dual-PSU ATX Adapter $10.00 Total $3,221.82 Kh/s 5208 Kh/$ 1.616477643071308 5 GPU system Power Supply $285.15 GPU 5x$377.36 $1,886.80 Total $2,171.95 Kh/s 3720 Kh/$ 1.712746610189001 So it looks like I would get more Kh/$ using just one PS and 5 GPUs. This assumes I can run 5 GPUs on just one 1200 watt PS which is yet to be seen. I suppose I could try a single 1600 watt PS for 7 GPUs but I really like the Corsair AX1200i because of it's monitoring features. Title: Re: My Custom Case Build Post by: CartmanSPC on August 17, 2013, 07:04:51 AM 4 GPU system
Power Supply $285.15 GPU 4x$377.36 $1,509.44 Total $1,794.59 Kh/s 2976 Kh/$ 1.658317498704439 The system has been mining with 3 GPUs for over a week now. The case brought down the temps so much that I now run the fans at 80% instead of 85% and increased the voltage from 1.100 to 1.125. Hash rate per card is up to 744 from 722. Just got the 4th GPU today. Will try to get updated pictures after I get the 4th GPU installed. Changed the way the power supply is installed since it will only have one now. I think I will be sticking to 4 GPU's per system since that should get me somewhere around 1000 watts (not sure yet as 1 was 300w, 2 was 500w and 3 took it to 800w). Trying to stay close to 80% of the PS's capacity so that is 960 watts out of 1200 watts.

Title: Re: My Custom Case Build Post by: CartmanSPC on August 19, 2013, 06:53:50 AM Thanks for that kslavik. I choose some more expensive options as I wasn't looking for the cheapest build but that looks like a nice list.
For anyone wondering here are the component costs. Waiting on an additional discount of between 10-30 on the last GPU. Not included is the aluminum cost of around $40-60 and the cost for the tools to build the case.

I used to use Tahiti XT2 to follow up, (now, Verde only) but it is too great that I have to send away until I have found a more suitable solution as You seldom upgrade anything once configured. Dip your rig in mineral oil, then You no longer need much space. If I had the amount, I shall try to build the oil rig. Title: Re: My Custom Case Build Post by: networkgeek24 on August 24, 2013, 03:44:41 AM Cartman - wanted to say thanks again for posting your setup. It inspired me on a new rack mount case for my next rig. Not quite done yet, but getting close. I wanted to fit 2 rigs in one and I think it will end up working.

Make sure to keep us updated on your progress! I ended up reversing the placement of the case in the rack since these MSI GPUs blow most of the air out the front of the cards instead of the back exhaust vents. It does not look like I'll need any additional fans to keep them cool. Thank you for everyone's encouragement. It really helped and pushed me to keep going. If you’re thinking of building your own case go for it! Although it was frustrating at times it turned out to be a fun project.…just make sure you have the right tools :) Title: Re: My Custom Case Build Post by: 18RATTT on August 24, 2013, 06:56:35 AM sweet setup Cartman.

It makes me want to go spend more money on GPUs, but I think those days are almost gone.

;) Title: Re: My Custom Case Build Post by: CartmanSPC on August 31, 2013, 02:50:14 AM nice work! Thanks!where you get the powered riser ? buyahash.com They have standard length and extended length. Also got the PS splitter from them. The extended length risers are really long though. Would be happy with just an extra 2" from the standard length version. Title: Re: My Custom Case Build Post by: CartmanSPC on September 03, 2013, 07:42:40 AM Ok, got a 5th card. Since I am maxed out at 4 cards with a 1200 watt power supply I had to get another power supply. I plan on eventually having two 4 card rigs but until I get more GPUs I will use the second rigs PS and GPUs in the first one.
Will also be running up against the max of 16 amps on the 20 amp circuit I have. May or may not be able to run 6 GPUs until I can get a higher amp circuit. At that point I will be switching to 208 volt from 120 I'm using now. The second power supply is also a Corsair AX1200i. This picture shows the two CorsairLink interface units. Since CorsairLink only supports reporting on one PS at a time I have to disable one and then enable the other (in device manager) to see it's individual power usage. A nice surprise was that even though some of the GPUs are being used on the second power supply, CorsairLink still see's them for monitoring. https://i.imgur.com/zqNArxo.jpg Here is a pic of the case with the GPUs now facing the front of the rack (cold air isle). You can also see the temporary orientation of the two power supplies. You might notice that I am only using powered risers on the first 4 GPUs. Think I'm okay not powering the 5th one. If I had 6 or 7 GPUs then I would break out another molex cable to the power supply. I may still do that just for the 5th GPU. https://i.imgur.com/vr9IlZF.jpg Close up of the connections. 1st power supply has 3 GPUs + 8pin MB + SATA power. 2nd power supply has 2 GPUs + 4 connector molex cable. I can now see that if this was going to be a permanent setup the case should of been made longer so there could be more space between the GPUs and power supplies. The additional space would facilitate easier cable management and allow some distance between the GPUs and the PS since these particular GPUs expel the majority of hot air towards the power supplies. Even with one PS a longer case to distance the PS from the GPUs would (I think) have been beneficial. https://i.imgur.com/hMvMfxG.jpg Title: Re: My Custom Case Build Post by: ZetaOS on September 03, 2013, 03:01:20 PM My friend nice setup you build.

Title: Re: My Custom Case Build Post by: guugll on September 04, 2013, 01:10:41 PM thx for reply - i was searching for this stuff.
your build is very nice - i have an inspiration. Title: Re: My Custom Case Build Post by: CartmanSPC on September 04, 2013, 11:13:10 PM cgminer running smoothly. Think I will increase the fans from 80 to 85%.
I suspect that GPU1 is actually the left most GPU and GPU0 is to the right of that one. https://i.imgur.com/Pd1CMCY.png Title: Re: My Custom Case Build Post by: kslavik on September 04, 2013, 11:59:25 PM cgminer running smoothly. Think I will increase the fans from 80 to 85% on the first two GPUs. The processor is right under those two so I'm thinking that's why they are 10 degrees hotter. I suspect that GPU1 is actually the left most GPU and GPU0 is to the right of that one. What are your settings for 7970: engine, memory, voltage, thread count and bios version? I have the same MSI 7970, but it just refuses to go past 660 and at the same time I can get 7950 to mine at the same speed. Thanks Title: Re: My Custom Case Build Post by: CartmanSPC on September 05, 2013, 06:24:57 AM Try 1055/1500...or better yet come to IRC and we can help you there.

Very nice build man... much envy going your way for sure. Are you just using the card fans to cool? or do you have anything else pushing air through them? It's gotta be pretty warm around that thing. Title: Re: My Custom Case Build Post by: krayzie32 on September 06, 2013, 07:50:41 PM Eh... That MSI is about 250 now... Hope you waited to buy... Case looks great tho. Thanks! Where is the MSI 7970 selling for $250?! The cheapest I have been able to find is $377.36 after tax and rebates. Funny what less than a month can do for GPU pricing, 7970s can be had for 279 right now on Newegg after rebate. Great looking rig BTW. Title: Re: My Custom Case Build Post by: CartmanSPC on September 06, 2013, 08:29:43 PM Are you just using the card fans to cool? or do you have anything else pushing air through them? It's gotta be pretty warm around that thing. Just the card fans. Ambient temperature is 68 degrees. Found that one of the GPUs was running hotter than the rest so I moved it to the coolest spot in the rig. I'm sure it's due to the thermal paste not being put on correctly from what I have read. Temps after moving GPUs around. I have pretty much confirmed that GPU 0 is actually the second physical GPU from left to right in the rig.

Great looking rig BTW. Yup, that's why I went ahead and bought another one :) The ones I use are just a bit pricier than the cheapest ones and temporarily went down to $299 after rebate. They are up to $344 after rebate now..should of bought more but funds are a bit tight :( Title: Re: My Custom Case Build Post by: PMB on September 26, 2013, 09:04:18 AM The second power supply is also a Corsair AX1200i. This picture shows the two CorsairLink interface units. Since CorsairLink only supports reporting on one PS at a time I have to disable one and then enable the other (in device manager) to see it's individual power usage. A nice surprise was that even though some of the GPUs are being used on the second power supply, CorsairLink still see's them for monitoring. Hi! Nice setup!!! Very clean! A change from the confusion of cables We usually see :-) I've been thinking of linking 2 psu's together, what did you use to link the 2 psu's? regards, P. Title: Re: My Custom Case Build Post by: BTC Electronic LTD on September 26, 2013, 04:10:45 PM We have the OEM case too.

To connect the two PSUs together I am using this adaptor from buyahash: http://buyahash.com/product/dual-psu-24-pin-cable-adapter/ There is another adaptor you can use from www.add2psu.com but it requires a molex connector.

Heck, If I make anything at all it's all gravy 8) Unfortunately my attention has drifted elsewhere so I'm not into it as much. Title: Re: My Custom Case Build Post by: Zeek_W on October 02, 2013, 10:57:07 AM In my head I like to read this thread with the post dates a year prior and marvell at it lol.
In all seriousness - great setup! If all else fails you can use it as a render farm or rent for WPA cracking Title: Re: My Custom Case Build Post by: ZetaOS on October 08, 2013, 12:32:58 AM love to see this rig of yours whit this cards instead of videocards.

BFL cant make that card its too powerfull for the size of the tech that exists and cooling it would need min water cooling tower. Have a word with ya self lol Title: Re: My Custom Case Build Post by: CartmanSPC on December 01, 2013, 08:10:31 AM Finally got another card installed for a total of 6. I am at my power limit (15.656 amps) so this will be it until I can get more utility power.

and how are you securing the cards are you using an inner frame just for the gpus.. is that the metal i see on the sides? I was thinking of doing this and i ended up just grabbing a pre fab.. Cheers Title: Re: My Custom Case Build Post by: CartmanSPC on December 05, 2013, 10:38:05 PM Thanks zedicus!
I have enough clearance to have just a bit of space between the CPU fan and bottom of the PCIe riser cards. On the top side there is enough to clear the power cables in case I decided to enclose the case with a top. Currently the cards are not secured to the inner frame. They are just resting on it. In earlier pictures I showed and had planned to secure the cards with another piece of aluminum but the spacing for it was lost due to the rivet being too low. Not a big deal as it will not need to be moved but when it does the GPUs will need to be removed. 6 GPUs may be the max this case will support utilizing just the stock GPU fans. 7 may make them too cramped to allow adequate airflow. Title: Re: My Custom Case Build Post by: CartmanSPC on January 06, 2014, 08:55:51 PM 6 GPUs may be the max this case will support utilizing just the stock GPU fans. 7 may make them too cramped to allow adequate airflow. So with 6 GPUs the temps were getting into the low 80's even with the GPU fans bumped up to 90%. It was time to figure out a way to cool the GPUs some more so I decided to try adding auxiliary fans. It blew me away how much this helped! (2) 200mm fans and GPU fans back down to 80%: https://i.imgur.com/fXvFXuB.png From left to right GPU#s: 2 0 3 4 5 1 https://i.imgur.com/XtJy9vb.jpg These 200mm fans fit almost perfect. I could drill holes to secure them but will most likely just use zip ties. If I ever make another case I may try to fit them inside the space between the front/back (depending on how you look at it) of the case and the GPUs. Yes, they are blowing air at the GPU exhaust vents since these particular models mostly expel air the other way. They are plugged into motherboard fan connectors and are not running at full speed. Very happy with the results and surprised that it helped as much as it did. Title: Re: My Custom Case Build Post by: cp1 on January 06, 2014, 10:06:13 PM I wonder what another two at the other side and enclosing the case would do.
Title: Re: My Custom Case Build Post by: CartmanSPC on January 06, 2014, 10:12:58 PM I wonder what another two at the other side and enclosing the case would do. That was my original plan...would be interesting to see! Datacenter has not complained about the open rig yet but if they do I may have to enclose it. Title: Re: My Custom Case Build Post by: cyclops on January 06, 2014, 11:19:11 PM Fantastic Build, but how do you manage to boot all the cards without display? Dummy plug?

Title: Re: My Custom Case Build Post by: CartmanSPC on January 07, 2014, 07:32:55 PM Fantastic Build, but how do you manage to boot all the cards without display? Dummy plug? It's hard to see but I have a Displayport to VGA adaptor in GPU0. That is going to an IP KVM. Looks fantastic man Cart, amazing, love the twin fan setup I know huh? Did not realize the two 200mm fans would fit so well. Imagine if they were embedded into the frame design? That would have been cool.Very nice build - really gives me something to think about....build my own alu, pvc or buy. If I had the option to buy I would. Building the case was fun but a lot of work...especially for someone who has not picked up a power tool in 15+ years. At the time I started there was not a case option that fit into a 19" rack. I still don't think there is one available. I looked at farming out the work but was getting quotes in the $400 range. I stared this thread because the guys in IRC asked that I document the build. I tried to post what I learned in the process. It is also nice to have something to reference if I build another one. If you have the time, patience and tools to make one yourself go for it! Please post pictures :) Title: Re: My Custom Case Build Post by: cyclops on January 07, 2014, 09:34:19 PM Fantastic Build, but how do you manage to boot all the cards without display? Dummy plug?

I have never tried to run it without a monitor plugged into GPU0 so I really don't know. One tip....when using a Mini Displayport to VGA adaptor make sure it is an "Active" adaptor. Passive adaptors (like the one Apple sells) will only give you a resolution of 640x480. Knowing that would of saved me some frustration and a few trips to the store!

If I need another GPU case this is a nice option to have.

It has been shut down and is in the process of being dismantled. For most of it's life it was mining scrypt but towards the end when the GPU fans gave out (and they ALL gave out eventually) it was transitioned to X11.
One of the power supplies has found a new home in an A2 Mega Terminator.
