My Custom Gridseed Case Build

[CartmanSPC]

OMG dude...never thought to modify server power supplies for these.... I run a BUNCH of HP Server and that breakout board pmorici has that interfaces with the DPS-800GB-A looks good...also the Home Depot solution you posted for the  Delta DPS-835AB, Artesyn 7001138-Y000, IBM x3650 3655 835W (12.1V 69A) power supplies is brilliant!

....and these server power supplies have plenty of clearance for the case I just built! Too bad I already ordered 20mm extrusions for another case    Oh, well..give me an excuse to use the mider saw again

IBM power supply watts: 835w max.  80% of full load = 668w. 11 Gridseeds dual mining = 660w (60w x 11). 66 scrypt only mining = 660w (10w x 66).
IBM power supply amps: 69.0A max. 80% of full load = 55.2A. 11 Gridseeds dual mining = 55A (5A x 11). 66 scrypt only mining = 43.56A (0.66A x 66).

The HP at 1000w can push 800w (80%) for 13 dual mining or 80 scrypt!

And with that breakout board you could just plug in 12 stripped barrel plugs directly into it...man...so nice. It also connects to a Pi for remote on/off and monitoring. He said in a post that it cost him $30 to make though so it would be cheaper to do your $2.18 solution

Please post pictures of your setup with the gridseeds if you have time...if you can't tell im excited. Screw those $300 Corsair AX1200i's!

That's how I'm doing them: https://bitcointalk.org/index.php?topic=499132.msg6016723#msg6016723

I can't get you pictures of the other cases, only the dev case.  Everything else is racked in 3 or 4U chassis already.  I'm lazy and don't even mount the seeds, just stick them in on their sides.  I use 18AWG DC pigtails from the PSU and a 14 AWG jumper wire to power a 5Amp step down.  I run 4 way splitters off each DC barrel plug to power 4 seeds in scrypt only mode per lead.  (I think this picture has 12 cables for 48 seeds)  Desolder the fans to save space.  Good to go.  no issues.

[GAW Miners]

So enough time has past that I have forgotten how much effort it was to make my first custom case  

Using this forum post as my scratchpad for ideas, dimensions, etc.

First design idea (abandoned):

This time I will be making a case (most likely) out of acrylic sheets and metal rods to house Gridseed miners.
Dimensions will be similar to my first case as it will need to be mounted in a server rack.

Preliminary Dimensions
Length                       600mm
Width                        448mm
Height - Utility Shelf    133.35mm (5.25") 3U
       - Rod size            127mm (133.35 - 3.175 - 3.175 = 127)
Height - Miner Shelf        88.9mm (3.5") 2U
       - Rod size         85.725mm (88.9 - 3.175 = 85.725)
Holes                         97mm
Acrylic thickness          3.175mm (1/8" or 0.125")

Miner weight  0.9375 lbs x 20 = 18.75 lbs

Note: May reduce the rods length in the Utility Shelf section so the case can be removed without binding on adjacent rack equipment:  - 0.787mm (- 0.031")

Here is my inspiration:



Bottom level will be for power supply, USB hubs and controllers.

May quickly move from the supplied power supplies to a Corsair AX1200 (or AX1200i as I don't think their making the AX1200 anymore). This will require more space for the bottom level. Watching this thread for the required cables: https://bitcointalk.org/index.php?topic=74397.msg5492169#msg5492169

Top level will be for the Gridseed miners but unlike the picture I will have the fans blowing up. From here it can stack more levels depending on how much space the power supplies and accessories the bottom level can hold.

Looking at having a profession company cut the acrylic sheets.

Layout:

Red dots - location of the rods
Blue dot - main access hole for wires
Yellow dot - optional secondary access hole for wires (of course you can use any hole for miners or wires)

Picture of what I envision it looking like (wider with holes):

Second design idea (in progress):

Using 80/20 instead of acrylic.

Here is my new inspiration:


Dimensions
Length                       600mm
Width                        448mm
Height - 3U Utility Shelf    132.563mm (5.219")   *Note: 133.35mm (5.25") -  0.787mm (- 0.031")
Height - 3U Miner Shelf(s)   133.35mm (5.25")

Miner weight  0.9375 lbs x 20 = 18.75 lbs

*Note: Reduced the length in the Utility Shelf section so the case can be removed without binding on adjacent rack equipment:  - 0.787mm (- 0.031")



Cost
80/20 parts with shipping and tax: $157.87
Corner Braces: $

I like your inspiration

We have had great luck also with using Sidehack's Z750 dell > PCIE board, then PCIE > DC. HAve each dell powering ~30-45 without a problem.

I purchased 4 of the IBM power supplies. Plan to use the Offset Terminal Lugs miaviator discovered and these barrel plugs with 18 AWG wiring:



Any tips on where to buy the wiring? Home Depot did not have any 18 AWG and Radio Shack I'm sure is over priced.

i used 18-2 door bell with 50 feet was $7 and that for both strands. i hook up 20 units and still had a bunch left. been running on it over a week with no problems

Not it is sloid core wire not stranded so the wires are stiff and a little hard to manage.

Something like this should work:

100 FT 18 AWG GAUGE ZIP WIRE RED BLACK STRANDED COPPER POWER GROUND - $13.92

[vipgelsi]

Nice case design.

[CartmanSPC]

Thanks vipgelsi!

...on second thought I think ill save myself the bother and get Male 18 AWG DC Power cords with 5.5x2.1mm connectors like miaviator suggested.

Word of caution: I just measured the DC power cord that came with my miners and they are NOT 18 AWG. My gauge only goes up to 18 AWG but I would guess they are 20 or 22 AWG. Fine for scrypt (I would imagine) but not dual or SHA mining.

[CartmanSPC]

Since I switched to using 20mm extrusions (instead of 25mm) it opened up lower cost corner bracket options. These are not as inexpensive as the generic home depot corner brackets but they don't require any drilling (to enlarge the hole), are stronger, include alignment tabs and are made specifically for this application:

found a way to hide all the wires

and the whole setup is 175watts at the wall

Very nice DPoS. Looks like a city from the future.

thanks - hashing homes for us all

originally I was just going to shove them all in a PC case but they looked too good not to make it a display.. and without the fans and it being wireless networked I can move it and plug it in anywhere    

it runs Win7 so I just remote desktop into it to kick off the cgminers (will make a startup script on boot as well)

You should check out cgwatcher if you haven't already. Use it for my GPU rigs. It supports auto starting of cgminer on system boot, email notifications, and so much more.

[CartmanSPC]

This is a nice looking case! Not very efficient use of space but still...nicely done.

Don't know the dimensions but it appears to be rack mountable. Not sure if they are selling it on it's own but it comes in a bundle with a PS, 20 port USB hub, and Pi for an extra $250.

[CartmanSPC]

All done!
Currently the top section/shelf is in the universal position as I wanted to try different mounting options. Going to move them closer together for the "on the side" position even though it could just be left as is. If I get more miners I will add a second or even third section/shelf.

[roslinpl]

Omg. Now I am so jealous ...

I just read this thread and after watching all of those pics ...

Great stuff! Nice cases ... and I do like Gridseeds ... so all together was really nice to see and read.

I would like to see pics with it all wired up.

LOL, I knew someone would call me out on that!

Still waiting on the barrel plugs to come in on the slow boat from China (just tried tracking its latest location and the map literally shows it on a boat).
Ended up getting copper 16 AWG wire. Also need to buy some wire strippers or borrow a co-workers.

Have 18 AWG DC pigtails I might use if I get impatient. Also have 6 way splitters for scrypt but need to cut one open to see what wire gauge it has.
