removing the stock fan grills was my first attempt to mod a case.
Added a 120mm and an 80mm hole to a case that only had two 80's.
Bigger fan holes Blow, more air
Overclock the life out of that 9500
friend of mine witha p4 @ 3.25 and a 9500 pro gets 17500 in 3dmark 01
course its a lil unstable, but he can complete a loop of 3dmark 01
if he had better video card cooling it would be completely stable i believe
i think he was like 100mhz overclock on the core of his 9500pro
see what you can do
he also had his 9500pro flashed to a 9700pro bios
cant say i recomend trying that, but it seemed to work on his cause his card is always reconized as a 9700pro now at 9500 clocks
