7200rpm drives would be great in here,load times for games,but the 4200prm will generate less heat.A 160g drive can hold alot of game images,all you need to do is wait 5 seconds more.
btw:To run Quake3 on lcd properly @max res.
1. run the game at least once (as I'm sure you have).
2. go into the baseq3 folder and open up the .cfg file in wordpad.
3. make the following changes:
seta r_customheight "900"
seta r_customwidth "1440"
seta r_mode "-1"
seta cg_fov "105"
4. Save
