Lovely video, but that's starting out with a $3,200/$3,300 case/motherboard + processors + video cards + memory sticks.  Does address the PSU problem nicely and it says it was designed around cooling 8 cards.  Fans seem top quality, but very loud.  I think Yun9999's Rosewill versions with maybe only 6 1080 Ti's is a better deal.

Link to a miner?

No.  I thought you were genuinely interested?  If you want to see these cases stacked really high, find the Man Cave thread and go to the beginning of that.

Okay, go to the link below.  This build is using a HP 1500 common slot PSU with an eBay heat sink screwed to the lid.  Two 80mm Delta fans in the back, plus a double-fan blade Delta to push air over the HP heat sink fins towards the front of the case (drilled a few holes on the outside of the case).  And you can see the Dynamat material lining parts of the case to help with noise/vibrations.  This was an L-4500 where you have to remove the fan cases and all that junk.  The EVGA FTW and FTW3 cards are a tad too tall for the 4U case if you want to put the lid on.  But you can fit EVGA 1080 Ti SC and SC2 models inside just fine.  An Aorous 1080 Ti Extreme will also fit with room for cabling and you can put the top back on.  Of course, smaller cards are less of an issue.  Get the SC or SC2 over the FTW EVGA models if you can.

I placed some non-conductive material underneath the breakout board you see connected to the HP psu.  The heat sink keeps the HP fan from spinning way up; I found that with a heat sink, the HP psu supplies are very quiet.

You can see a Lamptron 5-fan controller in one photo I place that on the inside of the case right below where you see it perched in one of the shots.  This controls the 3 Delta 120mm fans up front.  I use a fan Y-adapter cable + fan cable extenders to take the 2 80mm fans back to the Lamptron.  That left one connection for the double fanned Delta above the HP psu.  I use fan cable extenders to reach the Lamptron.

With this psu and breakout board, you need some 6 pin -> 8 pin adapters/splitters.  The 1070s draw 150 watts or less depending on what I am mining, so I don't feel that presents any issue.

I apologize in that the pictures I took today did not come out so I will come back with some photos of all the cabling in place.  You can get the tops on if you avoid the FTW/FTW3 cards.  Cooling is fine using the Delta fans.  I have the Lamptron turned to about the 1 o'clock position instead of the maximum which would be around 5 o'clock on the knob.  Currently, I have two stacked -- one directly on top of the other.  No issues so far.  What is counterintuitive is that the cooling works out as well as an open air frame with no more noise if you turn the fans down.

Pros: High partner acceptance factor; doesn't look all that much different from some of the stereo equipment that I had in the past.  Quiet.  Good temperatures.  Cuts down on the LED light show.

Cons:  First build is frustrating.  Costs more than open air rig.  Have to be creative when fitting a server PSU into these as they are designed for screwing in a typical computer ATX power supply.

I may be wrong, but I'm pretty sure that it requires a fixed IP address (that would be standard for masternode coins). That's why many people rent a VPS to set it up, or pay for a service that includes VPS and setup done by them etc.... I have contacted NODEShare about Solaris and they have expressed interest in adding it. They pretty much do it all for you and I think would be worth the fee they charge if they do choose to add Solaris.

How can others contact nodeshare?  I didn't see any addresses on the website where I could request that they add Solaris.

Thanks.

Sure, I'll link to some pictures this weekend.

Okay, today I put together a RoseWill L-4500 using one of Rick's [older] brackets.  It went much faster this time, but the nuts and bolts are very small and this does require some patience.  Using your kids to help out threading the tiny nuts to the small bolts is a good idea, if that is an option.  I simply had to put on my reading glasses and I was okay.

I got the L-4500 for $105 at Walmart online, so we are no longer talking about $200 just for the case.  I prefer the L-4500 build over the L-4000B because I do like those metal fan cages that are reused in the front.

This may be obvious, but assemble the frame and put your GPUs in first, and then think about installing your motherboard.  Rick's new manual does have a link on how to take apart the L-4500.  The YouTube video is pretty helpful.

Yes, getting the front off requires removing screws on the bottom, the sides, the top, everywhere.  And you end up removing all the metal fan cages, a middle fan bracket, and other junk.  
Yes, you need to remove the fans that come with, and instead go with (3) Delta 120mm fans in the front and (2) Delta 80mm fans in the back.  You literally swap out the generic crap fans with your Deltas and you are good to go.  Or you can contact users here who sell similar fans for only $10 a pop instead of $20.  PM hawkfish007 for a cheaper alternative to the Delta fans that still moves a lot of air.

Building this inevitably involves not tightening everything down super-tight the first go round.  You end up making lots of small changes, adjustments, and then you finally get to a point where you can lock things down.

Dynamat sound absorber lining the bottom gets rid on weird high pitched sounds.  The Lamptron fan controller is the way to go for controlling all 5 of your fans' speeds (volume).

Took 2 hours this time to get everything assembled, GPU's installed, but I'm not counting dropping in the motherboard.

I am stacking these.  Rick's frame is very good and I would recommend it.

Finally: Sure, if you can go with open air rigs, you can build those cheaper.  But open air frames do take up more space.

I use mine *with* the top on.  User a server PSU, use 6 pin cables for your risers, use 6-pin to 8-pin cables for your video cards.  Rick's frame lowers the video cards and you can insert cables and get the top on.

<snip>

In my opinion, the 4500 case is for a hobbyist that wants to try a build. It isn't for anyone building mining rigs at scale.
[/quote]

I agree that this was not a fun or easy build.  That said, I've been running mine with the top on and it is doing just fine.  I have 4 1080 Ti cards in there + 1 1050 Ti plugged into the main motherboard slot.  Temps are good with the Delta fans.  With a Lamptron 5 fan controller, you can dial down the speed, thus reducing the fan noise.

The first time you do any build like this, it is always difficult.  With each successive build it becomes quicker and easier.

Cost:  Yes, this is not a cheap solution.  But my partner hated my open air rig on the floor.  This case + Rick's bracket solved that problem.

Yes, that middle fan bracket is useless with large cards, and I removed it.  With two Delta 80mm fans in back, no issue with ventilation.

I struggled and cussed while I put this together, but with Rick's frame the case is functional.

Rick is working on a frame that floats a server PSU over the motherboard, much like a compact computer case does.  You can also remove the two Rosewill brackets, drill some holes into the side of your case, and make your own bracket to support a PSU over the motherboard.  That's what I did, but Rick's solution looks nicer.

One final thought:  I don't think it is fair to criticize Rick about not providing instructions for how to take the case apart.  YouTube has some videos that are worth watching, like this one: https://www.youtube.com/watch?v=BEsev9vTeHI

Hi,

Thought I would give SimpleOS a try.

I want to completely delete the default "rig" or "group" that is set to ETH + SIA.  I can't find any button that allows me to do this.  Before someone suggests I rtm, there are 262 pages of posts on this thread and next to nothing in the way of help on the web interface.

I've set up a miner and set it as the "default" but the OS keeps trying to launch the "default" configuration.  How do I switch to the Miner/Pool that I just entered all the info for?

Thanks in advance.

Very clever work.  I was impressed by your support bracket for the 2nd HP PSU and the PCIe expansion board which makes up for the blocked slot.  The one problem that I see is that bigger cards would push too far back to allow for the same orientation of the HP PSU.  But with smaller cards that's a nice setup.

What did you make the fan brackets out of?  I don't recognize what you are using and was wondering whether it's custom, or repurposed from something else.

I would try Delta fans if that is not what is shown in the video.

Looks good.  Using a low profile CoolerMaster CPU fan for an LGA 1150 or LGA 1151 build and that should be fine height-wise.  Also, a stock Ryzen fan should fit underneath the PSU with some room for clearance.

The other option would be to talk to SideHack or Price Technology and get the screw-in terminal type of break out board as that would help with top of the case clearance (You would not have to deal with the fixed height of the 6-pin plugs on the breakout board, so you could lift the PSU a tad higher, which ought to help with CPU fan cooling.  I think only Price Technology would have the screw-in board for the 2000BB available immediately, but SideHack could make them if there was enough interest.

But that would mean removing the top 'square' part of your frame that sits on top of the PSU.  Why not run at least one of the horizontal mounts all the way to the side of the case where it could be secured with a screw?  You could keep the vertical posts but cut to the same exact height as the PSU, but remove that extra not quite 1" from  the top square part and get that much more clearance for CPU/CPU fan cooling.

One other item you might want to check:  order a mini EVGA GTX 1050 card and adjust your height so that the mini 1050 GTX card fits in the main PCIe slot.  That gives you an easy-to-access HDMI port for when you need to connect a monitor to the rig, and it will mine a little bit as well.  The big gun cards then can all go up front and connect back to the motherboard via the USB cables/risers.

I think that layout as you have shown will handle the PSU cooling just fine.

The only other option that I can see is to house the PSU outside the main 4U case and run longer than normal power cables to the GPUs, risers, and PICO psu.

Nice work.

Last point:  The Lamptron CF525 5-fan controller can be mounted up towards the front (Left side as you face the back of the case).  Running fan cable extenders allows you to quickly connect up the 3 Delta 120mm fans up front and then the 2 80mm Deltas (or equivalent) in the back.  I've found that the cooling is fine even when you dial the fan speed/noise level down.

Estimated cost at this point?

One question:  What is the third leg holding the platform connected to?  I see the two main legs.  EDIT:  never mind, just figured out the "leveraged" part of your description.

Depends.  If you set TDP to 60, Temp to 80, core to +120, mem to -500, it will get about 700 Sols for 173 watts.  Doesn't overclock well in my experience, though.

If it's cheap enough, I would go for it.

Review of Rick's drop in bracket using a Rosewill L-4000B.  

1st, I wish I had ordered the RoseWill L-4500 because I understand those cases are deeper.
2nd, probably a fine solution for smaller cards, but not great for 1080 Ti's.
3rd, this was a difficult, no fun, type of build.
4th, if you stick with high CFM Delta fans, temps won't be a problem.  Get a Lamptron CF525 5-fan controller and some fan cable extenders so that you can tune the fan speeds.  They do not need to run at full blast to cool large cards.

Rick's kit is complete: he includes tools, he labels all the bags so you don't have to guess at mm sizes.  His online manual is good, I just wish some of the pictures could be zoomed in on. I had an issue with one fan post, Rick promptly replaced it.  He included screws for my larger 38mm Delta fans and he left in the originals as well should I ever switch out the Deltas.

Rick's bracket solved most of the problems with this case.  

The Rosewill case only has one PSU opening in the back, but I put an IBM 2K (DPS2000BB) server PSU on its side and used one of Optimizer's excellent breakout boards.  I placed fans on top of the PSU to help it with cooling.  In the end, it was probably overkill.  I will get around to re-purposing both the riser support beam and the Rosewill GPU beam to make a horizontal platform to float the DPS2000B above the motherboard; that would allow me to place fans behind and in front of the psu and maximize air flow. I could then screw some additional intake fans over the psu opening in the back of the case.


The IBM psu + Optimizer's breakout board provides 15, 6-pin outlets.  (1) used for flminer's nice PICO power supply unit to supply power to the motherboard.  (2) used for a front fan controller speed box.

If you get the fatter 38mm Delta fans, there are some issues.  First, with the fat Delta fans, the bracket is not balanced and will tip over while you are assembling everything. And pay attention to Rick's photos on where to snake all the cables coming from the front of the case (between the side of one fan and Rick's bracket).  The screws/bolts that connect the black tabs to hold the fans to the frame are tiny and a bit difficult to work with.

The fan frame and mounting it inside the case is probably the most difficult part.  Slide the whole frame back just a notch if you are using the 38mm fans.  Make sure that the front door can be closed and locked before you tighten down the fan frame.

Rick's frame slightly lowers the card height, which is a positive.

Gpu support rack has to be carefully adjusted and re-adjusted as far as height goes, till you get it right.  When it comes time to locking down a card, you have to precisely align the philips screw dead center over the nut inside the gpu frame.  Once you get the screw into that nut, it provides a solid grip even on large fat cards like the Aorus Extreme.

Don't completely tighten down the riser supports on the bottom, leave a tiny bit of play in them in case you need to nudge a card over just a tad.  

The 2 riser support beams are well done and clever.  They solve the strain issue that you'll experience if you try to use the 4000B's support bracket, which is useless.  Same goes for the 4000B's mid case fan support bracket for 80mm fans.  If you install larger cards, there is no room for the fan bracket, and it would do very little anyways, as the Delta's move plenty of air.

I removed the silly metal side bracket that appears to be for a hard drive.  In its place (towards the front of the case) I installed a small motor controller.  I wired up the 3 Delta fans in parallel.  Then I took a 2-wire cable and ran that from the breakout board to the motor controller.  This lets me turn down the speed on the Delta units to balance speed/sound volume.

I placed a few basic Arctic 80mm fans on the top and one on the side of the IBM 2k PSU.  I also placed two strong 80mm Delta fans on the back of case sucking in air in the same direction as the large 120mm Delta fans exhaust air out the front.

Temps are very good.  With the Delta fans turned down a notch, and this being a nice cool night, without AC the temps are right around 48c +/- 2 degrees for 3 1080Ti's, and 2 1070's.  Better than I thought and this is with the top on.  I'm sure I could do a better job sealing air leaks around the front three fans with weather stripping, that might help the air pressure a bit.  I have lowered TDP to 70 in AfterBurner for all of the cards.  Temps are slightly better than a comparable open air rig.

I was not able to get the IBM 2K psu and 6 large cards into this case, mostly because the cards extend back so far (which is why I would like a slightly deeper case).  I settled on four cards facing the front using Rick's frame, and then one card slotted on the motherboard in the main PCI slot.  This allowed me to connect up a monitor to the back of the case.  And it allows for pretty good spacing between the four cards in front.

My partner hated the previous open frame on the floor.  But I am not crazy about this Rosewill case.  If I had lots of smaller cards, and I wanted to rack these, I might feel differently.  But for just a few rigs, I don't think these make sense.

Cost:

Rosewill 4000B case:    $120;
Rick's bracket with tabs for 38mm Delta fans,   $99;
3 Delta 120mm fans (FFB1212EHE)     $60;
Price Technology DPS2000BB 2K psu + breakout board,     $110,
2 x 80mm Delta fans, $18;
fan controller      $12;
5 pack of Arctic 80mm fans (used three around the PSU)   $18

The Price technology breakout board is very nice.  I have used HP PSUs and Parallelminer breakout boards, and the Price board seems a bit more substantial.

Pictures of how I placed everything are here:

After I posted the pics, I re-did the cabling layout so that it did not rest at all on the psu.  I added a third Arctic fan to the top of the psu as well.

I respect all your other posts which I have followed for some time.  But the advice to use Win 7 is just crazy, unless you purposely want to limit yourself to 1-5 gpu's.  If that is your goal, cool.  I've mined with Windows 7 as well.  But I don't find it more stable than Windows 10, at least not once you shut down the damn Windows 10 updates. Bitcointalk has good threads on how to stop Win10 updates.  Windows 8.1 is far, far more stable for mining than Windows 7 and it boots up in a fraction of the time if you are using an SSD.

Windows 7 was never noticeably more stable in my experience for 4, 5, 6 gpus - not for Ether, not for Monero, not for Zcash.

If you don't want to use Windows for mining, fine.  I understand that.  But you can get high hash rates using Windows, and Windows 10 is what you want if you are going for 4+ gpu's.  You are never going to get a stable 8 gpu RX470/480/570/580 rig running under Windows 7.  You can do so with the Asus Z270-A, and it is pretty easy to do if you use Windows 10.  Yes, that is an Intel build, but AMD4 boards with Windows 10 will easily handle 5 gpu's. The sixth can be tricky as I mentioned.

You didn't answer my question:  have you actually set up a Windows 10 miner on an AMD4 motherboard?  Your comments suggest to me that you haven't.

No disrespect intended, QuintLeo.  You are on my short list of people whose posts I regularly follow.

The IBM 2K power supply will fit pretty nicely in one of these even when flipped on its side, which the Delta 2.4K won't do.

You can find very nice break out boards for the IBM 2K sold by users on Bitcointalk.

Use XMR-Stak to mine on the CPU, you'll be pleasantly surprised.  If you are having issues getting more than 5 cards recognized (Nvidia) under Windows 10:

First check what build version of Windows 10 you are using.  If you can find an OEM version of 1507 load that and update to 1511 and the freeze all future Windows OS updates.  Okay?  Don't allow Windows to update to build 1703 for example.

When you've managed that, with all of your Nvidia cards connected to their risers, use Display Driver Uninstaller to remove all traces of the Nvidia driver.  Restart.  Reinstall the Nvidia driver.  Wait about 5 minutes.

You should be golden.

I am assuming you already updated your AMD chipset drivers, your Ethernet drivers, and so forth.

I have to disagree and I have to ask:  have you tried this?  I have and the issue isn't 3 versus 4 cards, as every AM4 MSI B350 board I've tried handles 5 cards without any problem.  The issue is getting 6 or more cards to be recognized and that is a Windows issue.  Specifically, build 1507 doesn't work very well at all, build 1511 is rock solid with 6 cards, build 1607(?) does 5 and sometimes does 6 but maybe you have to make use of one of the M.2 slots + adapter.

You had better have small cards such as 1060, 1070, RX 470, RX 480, RX 570, RX 580.

But yes, nagging does drive one to do many things one would not otherwise consider.

Anyone else get a "token expired" error when updating your user account settings and, if so, how did you solve?

Thanks.
