I got mine in, and it it got here before some of the parts I'd wanted to use for power got here. Doh!
So.. I hacked a bit. Used a PVC pipe rail system, to keep them vertically straight and well separated.
I tried powering 2 off a single "accessory" cable bundle on a PSU, but the wires would get rather warm, uncomfortably so.
However, 1 blade per accessory bundle was no problem. These, coupled with 2 PCIe (you can hack up a 6 or 8 pin PCIe extender similar to what is shown here) plugs each powering a blade and everything is up and stable - nothing running hot.
Cooling thus far has been a cinch - a box fan keeps them all running stable, and most just warm to the touch. The two bookending the cluster though do get rather hot, and I have plans to pick up some high-cfm 120mm fans to act as blowers which should work well.
I will be interested to see how the rack they have works cooling wise, it appears to be bottom up cooling which would be difficult to make work inside a cabinet. If there is an easy way to mount fans on the back though, pretty much everything is better with a few delta 200cfm fans chugging away
