Almost anything to do with computers, including building them and overclocking them, as well as doing a little bit of gaming. I've also been a drummer since about 1993.
My System
I built this computer. Some parts are older than others because it was born in March of 2008. The good people of Overclock.net helped me out.
First, I'll list the most relevant parts for this forum:
Speaker system: Klipsch ProMedia 2.1 with 16 AWG Monster XP cables with Neutrik (Rean) plugs
Sound card: X-Fi Titanium HD with LME49720 op-amps to replace the JRC 21140 op-amps. I'm still experimenting with this. :)
Now, on with the rest:
Case: Cooler Master 690 (the original one)
Motherboard: ASUS P8P67 EVO
CPU: i5-2500K @ 4.5 GHz
Cooler: Thermaltake Frio with very powerful aftermarket fans
Memory: 8 GB (2 x 4 GB) G.SKILL Ripjaws X, model F3-12800CL9D-8GBXL
Video card: GTX 780 (ASUS DirectCU II, overclocked to 1228 MHz core, 6300 MHz memory)
Storage drives: two 250 GB Samsung 840 EVO solid state drives, one for C: and the other for D:
OS: Windows 7 Home Premium 64-bit
Optical drives: two Samsung DVD-RW drives
PSU: Corsair HX650 (the original model, but I know that it's major overkill for my system - it was on sale at a very low price)
Monitor: Samsung 2253BW (1680 x 1050)
Mouse: Microsoft Intellimouse Optical (not 1.1A, but it's still a very good one, actually)
Keyboard: Filco Majestic with Cherry MX Blues and full NKRO
