i cant stand LED's. i have a XPS 720 and because i leave my computer on all the time, even when i'm trying to sleep, i had to go into the bios and turn them off. It was like having a spot light in my room when i was trying to sleep. Drove me nuts. Now if they had an on/off switch on the side of the case instead of needing to reboot and go into the bios to turn them on/off i might keep them on while i use my cpu. Especially with that fun plug in that lets them flash and change colour based on what sounds music/movies/games etc are making.
