The Most Cost Effective Mining Rig?

[CYPER]

I am one step away from buying the rig, but just want confirmation I haven't missed anything:

4x XFX 5870
GIGABYTE GA-770T-D3L (has 1 x16 slot and 4 x1 slots)
AMD Sempron 140 2.7GHz AM3 (do you think it might cause 100% CPU usage under Linux?)
Kingston KVR1333D3N9/2G ValueRAM / 2GB 1333MHz
Corsair HX850 - 2 different reviews has confirmed it can output 1000W if needed.
4x PCI Express Riser Card Flexible Cable Adapter PCIe x1
2 x Coolermaster SickleFLow Blue LED Quiet Case Fan 120mm  (will be positioned on top of the cards for additional airflow)
8GB USB Flash Drive to install Ubuntu or LinuxCoin on
USB Wifi Dongle (not using wired connection)


No case, but DIY project
No monitor, mouse or keyboard needed

I would expect 1.6Ghash/s from it when overclocked = 180W max for each card

Any suggestions or comments are more than welcome.

Nice rig.

How much does that cost to build?

I run a very similar system w/ 3x Sapphire 5830s (haven't gone the riser route to fit a 4th).

More project right now is to build out expansion slot rigging, there's a lot of cool ideas in the Miners Forum.

Btw I just bought it - 1 hour ago.

Now I need to be patient and wait for the components to arrive and then I can proceed to assemble it.
I'll report back if there are any troubles
