When I finished building my ITX gaming rig I said:
"...I consider this build to be complete; this machine is as fast and quiet as it can go without significant further expense or modification"
I need more FPS so it's time to spend a bit of money and cut some metal!
Like the CPU heatsink, the idea is to cram in the biggset graphics card I can fit. The 6870 at 9.5" is pretty much the biggest card that will fit but I can fix that, I'll cut a graphics card sized hole on the front of the chassis but spare the front panel to keep the mod to be discreet. The mod will give me almost 11" to play with... *snigger*
So, uh. What the fastest card that will fit?
