Actually I think all of those extra pins are for signals and not for power, so the only thing you would lose with a 'shorter' slot is performance. Another thing you could (at least in theory) do is the remove the rearmost bit of plastic from the slot on the motherboard so a longer card could fit. I do know that there exist some motherboards with 'open' rear-ends of PCI-E x4 slots precisley to make it possible put a longer card there. (Assuming it does not interfere with any other components on the motherboard anyway.) The general rule with PCI-E is that if you can physically fit a card into a slot it should work. (Althouh there do of course exist exceptions with some cards and motherboards.) -- <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se
