I love my new computer.
I'm still getting used to the quirks of Windows 7, but I actually like that, and have very few legit complaints about the OS. The water cooling makes the system crazy quiet, to the point where it actually kinda freaks me out that it makes almost no noise. I suspect it disturbs me because I can hear the voices in my head that much clearer now...
The one thing, the ONLY THING, that drives me up the wall is that I can't use Power DVD 6 anymore, since that won't work in Win7, and I have yet to find ANY DVD player that comes anywhere close to working well enough for me. VLC comes the closest, but it's still not great. =/
