mickypheonix :
sorry for the late reply i have been doing my best to research a solution for you,
as far as a 770 that will fit in your case in the first slot i have found these two
Galaxy GeForce GTX 770 GC 2GB @ 254 mm x 111.2 mm
Inno3D Geforce GTX 770 2GB OC 1071MHz @ 255 mm x 111mm
you said the Gigabyte GeForce GTX 770 OC Edition 2GB card overlaps by about 2cm which is 292mm long
so that gives you about 37mm smaller so either of these cards should fit lengthways
will there be an issue with closing the case door if a card in the first pcie slot ?
well yes, it has the handle inside, so I can secure the case, I mean the cap has one, its a handle from the inside about 3 cm pops up.
the card I have can be attached by length almost, I mean it can be done, but I cant close the case and the power adapters doesnt work. If i dont close the case I will obviously have an issue, i can purchase another model if needed for better quality, one that might also need 6 pins would be useful too.
Well I dont much care as long as I have the gtx770 installed. the quadro one seemed to be too small in comparison with the "monster" card I just got.
so not the length is our problem but the width, it doesnt overlap any components because I switched it with my quadro.
well of course I want to get the best quality (from the best company) so I have a good manufacturer.
