Gigabyte EP45-UD3P Snow Leopard install
The Snow Leopard install on Gigabyte EP45-UD3P mother board works great. To save some money, use the Invidia 8400 GS video card for $39 and don't bother with 1066 memory, it doesn't recognize it. Get the Q8400 2.66Gig CPU for $134 and put a super cooler on it for $25 and over-clock it to 3.2 gig. Get the Mac Pro keyboard and mouse from Macally for $29.
I used the "How to build a Hackintosh - LifeHacker" web site. It Works!!!
I love my $2500 mac Pro!! (for under $700)
