If you cant find motherboard trays for cheep, just grind off the part of the brass screw that screws into the tray.  Then all you have to do is screw them on the motherboard and glue them to the metal tray.

Nice keyboard you got there... Nice...

[AssemblY]

Very good! I will try to make a equal to its. 

[cablepair]

thats slick man, excellent work.

[hmongotaku]

nice guide but i'll stick to a case. Main reason is it's portable and for 99 dollars I can get a decent case for another 50 bucks. Those 8 dollar pci-e extension cable ain't cheap either. I'll problably think about it when I magically hit the lottery. Good guide tho! 1+

Can u post with all cards, mother board, cpu attached & mining with pictures?

[d.james]

This looks like a perfect weekend project for me.
As the price dips I finally have excuses to take some of my rigs offline.

Suppliers and Source material
The aluminum tubing and connectors were purchased from http://www.brunnerent.com/ - There may be cheaper suppliers but for a no hassle, nice shopping cart order system, this is the pace to go.
The power supply is a Corsair AX1200
The motherboard is a 890AFX-GD70
The riser cables are cablesaurus brand. http://www.cablesaurus.com/

Any other suggestions of motherboards that can run 4+ gpus?

Protip: Do not try using a pneumatic hammer for assembling these. I tried it, and my wrist is going to ache for a week now. Going back to my trusty old shot-filled hammer. This is what I was using:

It kind of worked, but was slow and ineffective. Also it sprayed oil everywhere

You made me lulz.

Hi,

how are those cables called that "extend" the PCIe bus (the cables that connect the PCIe slots with the graphics cards).

I didn't know there's such a thing!

cheers,

I googled "pci-e extender" and got this:

everyone seems to swear by Cablesaurus (http://cablesaurus.com/), so I bought a few from them and they work fine.  If you search through the forums there are some cases of cheap PCIe extenders frying/burning up.  Their prices seem fair enough and their shipping is quick.

do they diminish the power to the card?  i see that some come with molex connectors.

[tinman951]

Not the card, but they protect the mother board from "blowing a fuse" because of too much power draw.  For instance if you have 4+ 7970s on one mobo you are drawing a great deal of power directly from the mother board.  The molex connector can give you power directly from the power supply; then only a little power actually comes from the mobo, only the data.

The very thin wires in the extenders do cause a bit more current to flow because of their added resistance. Rule of thumb is any and all dual-gpu cards with extenders should have molexes as well, and single gpu cards should be OK without them. However, the 7970 is a beast that needs more power, so it might be a good idea to have molexes, especially if you plan on overclocking.

Let me know if you start selling a kit. I am interested!! Have BTC burning a hole in my digital back pocket!
