Lowest motherboard/system

[cparsley]

you would try putting 2x+ graphics cards in to mine with? Just wondering.

You can really use just about anything as long as there is enough clearance for the cards to breathe. In reference, you want to make sure there is a minimum of 1 inch space between cards. The more the better.

any suggestions for board/system?
