[Beowulf] power supply/chassis for Opteron-based node

I've had good luck with this case: RM-4015 (no brand name)
http://rackmountmart.com/rm4u/rm4015.htm (no commercial plug intended)

It is big, and heavy, and well made. It has a fanwall with 3 X 120MM
fans. You can also add 2 rear panel fans, but you probably won't need
them.

It keeps a dual opteron motherboard nice and cool, and it is cheap.

I've had good luck with Antec true power 2 550 Watt EPS power supplies.
