Just thought Id show off my work in progress thats going to run the following.
GIGABYTE GA-990FXA-UD5
PC Power and cooling 1kw
AMD Sempron 145
1GB Crucial
160GB
DVD-ROM
5x 5830's
Windows 7
And my custom chassis, Upgradable in future for dual psu and 6990's. Its made for about 5-6 Video cards.
I know its very big, but I want good cooling and Expandable. Plan on stacking few on top of each other doing about 1.4gh/s each.
