I have a Thermaltake Spacecraft VF-I case which indicates that it has the capacity of 320mm length for a GPU. I read the features about the case on the website and was wondering if I can get any of your thoughts about this since I am purchasing a Sapphire Vapor-X R9 280X Tri-x 3GB GDDR5 OC which has a length of 308mm a few weeks from now.
The card that was featured on the casing was a HD 6990 which is 12 inches in length. I converted it to millimeters and surprisingly it's a few millimeters off at 304mm than the Vapor-X R9 280X Tri-X.
I converted the Sapphire card to inches, which has a difference of an inch and 1/4 I think from the HD 6990. Is that a big difference already? Gi setup na nako akong hard drive on the lower bay na para matanaw nako but naglibog ko if masulod ba jud.
Here's a reference of my casing and a HD 6990 graphics card being installed. This is the only pic I could find that you guys can see.
I'm afraid the card won't fit nya.

Bago lang ko nka assemble ug rig sa pagbasa2 nako sa inyo mga threads diri and with the help of PCgamer and Maximum PC magazines. Mao ni ako last piece para ma complete na ako dream come true na gaming rig.
Does any one here have a mid tower case that has the same capacity as 320mm for the gpu then has a gpu na same length with the Vapor-X Tri-x and wla nagproblema sa length pag.install?
