Well I may just go with a 680 then. What is the issue I hear about the ST45SF-G with the Hard Drives and all? Can I still fit two 2.5 inch drives along with a optical drive? Including jamming in a 680 and a Corsair H60?
Yes, 2.5" drives are fine, it's the 3.5" cage that is in the way of the modular cables coming out of the ST45SF-G
The reference design is 10.5 inches, but nvidia allowed them to design their own boards, and most have done that w/ their cheaper coolers. A look on newegg shows most of the twin cooler 770's listed as 10 inches.
For the FT03-mini though, twin coolers are going to run hot. The EVGA GTX 680 with reference cooler was already relatively hot in this case. EVGA and PNY are the only ones showing a closed-shroud cooling design for the 770, but they both use the reference PCB so they are too long.
I'm not sure what the market share is of SG05/SG06/FT03-mini owners -- perhaps it's inconsequential for GPU OEMs. Seems anyway like they are not concerned about the difference between 10" and 10.5".
