i have 3x6950 and (soon) 1x5830/50/70 to add.
currently all cards have ben risen with (duh) riser cables and are suspended over the motherboard in the usual fashion (ie some strange construction, selfmade).
i was thinking, now:
If I get two PCIEx16 to PCIEx1 splitters and plug them in, use riser cables to connect 4 cards to each of them and suspend them somehow so that I can get them cooled, I could - if I use one or two additional PSUs just to power the cards - potentially run up to 8 cards on my rig, right?
I would "just" need four more cards and two PSUs that I exclusively use to power the cards. No additional rig, motherboard etc etc. Only one remoteadminthingamabob and no more whatsits.
