Do I use CM or Inches to measure? And the Tuner can be removed I dont use it. As for the Card Marcopolo listed its a bit too high for me and I don't think that would fit. And the first two PSUs you listed are way over the price than what I picked out. I picked 750 because it has more room for expansion I won't have to buy a new PSU again unless it broke.
Since you have alsready decided on chipset saves us the trouble
PSU looks fine for the built you can even use a Corsair 650W that leaves you room if SLI in future.
As for the 680 it should be the same size as the 670 right?
Yes as long you buy the external exaust nvidia factory model .
Imomun what do you mean by that? Sorry Im clueless. I decided to buy the 670 FTW instead of the 680. I checked reviews and the only difference it 680 had a bit more fps. And I could use that extra money to upgrade my ram
My apology, I was saying that the one looks like my link is a reference design from nvidia rather than any custom designs as others has suggested.
So if you buy a reference pcb GTX680 thats the size of 670 FTW Product Dimensions: 9.5 x 2 x 4.4 inches
The exhaust version are the ones with the single fan at the end of the card
