I noticed the Antec One Hundred has 8 expansion slots, so I got the idea for a "cheap" folding setup when I saw this $50 case and the new dual GTX 460 card.

MSI 890FXA-GD70 AM3 AMD 890FX Motherboard
AMD Phenom II X6 1100T Black Edition Thuban 3.3GHz
Kingston 2GB (2 x 1GB) 240-Pin DDR3 SDRAM DDR3 1333
EVGA 02G-P3-1387-KR GeForce GTX 460 2Win
Kingston SSDNow S100 SS100S2/16G 2.5" 16GB SATA II
Antec High Current Pro HCP-1200 1200W

The MSI board is perfect because it's nowhere near the cost of the 1155 9-slot board or the SR-2, but it can hold 8 GPUs across 4 cards. That with a 6-core Phenom II makes a ton of sense, I think. With shipping, this costs $2613.18.

What do you think? Can you set up a better configuration (same or more PPD) for a similar cost?

For folding you actually want to have good RAM with good speed/timings. Doesn't have to be plenty. You may also want it for having to support a LOT of GPUs.

will that psu be enough?

I'd be surprised if that PSU would be enough. I'm not sure there exists a single PSU out that could support 8 GPU full load.

The PSU should do just fine IMO. It has 8 6+2 connectors. It's good enough for 1200W continuously with more power on the 12V rails than the 1500W Silverstone PSU.

Receiver, you asked if the 1200W power supply would be good enough for 4 GTX 460 GPUs, and sure. Why wouldn't something like a 600W PSU (continuous, not max) be good enough for a pair of 460s? And then, you'd only be running one motherboard rather than two (4 GPUs across 2 cards on one board).

That 1200W PSU would be ever so slightly along the lines of overkill for 4 460s. Ask the Atlas Folder guy what PSU he uses for his 4 GTX 295s per motherboard...

Though it has more Amps individually, you have to recall that is not a summation. The total number of Amps available to the 12V rails comes out to 99A or 1188W not 8*30A which would be a ludicrous 2,880 watts.

A not totally unrealistic test run of a fully stressed 460 1GB measured draws of between 188-200W. Assuming 188W from a folding load to be reasonable, and there's no reason to think the 2WIN is power saving, that's 8*188W = 1504W, far more than this PSU is capable of. And with a CPU and HD and fans and etc, more than even the 1500W Silverstone is capable of.
