This is my first build ever, and it's the first time I've ever worked with computers internally. Always been interested in building but never got around to it until now.
I use it mostly for gaming and simple tasks like web browsing, movies, and music....so it's essentially an HTPC with a focus on gaming.
This thing has been runnin like a dream. The case fans work really well at keeping everything cool, even with BF3 almost maxed out. Never seen temps over 40 degrees celsius. The fans can hum a bit on medium and high, but nothin that would make you upset.
My GTX 660 performs surprisingly well with everything I've thrown at it, and I haven't even gotten around to overclocking it. Only thing I can't really run on max is Metro: LL, although I believe with some OC doctoring I could get darn close to it while maintaining a pretty good frame rate.
No problems as of yet! Everything works like a dream, and I'm loving every bit of this build!
