I wanted an HTPC w/as few components as possible, hopefully to cut down on sound and heat. The plan is to stream my media through the computer in the back (which has two TB just for movies/TV shows, as I'm a Blu-Ray fanatic. I'm also a casual gamer.) So:

Case: Zalman HD135
Mobo: Asus P5QPL-AM, although I just ordered a Gigabyte GA-EP43-UD3L. Not sure if I'm actually going to need it, however. From what I understand, I will need a different motherboard in order to get better sound, and since this is going to be the entertainment center in my living room, I think I have to upgrade to a full ATX. (The current setup doesn't allow for a separate sound card, thanks to the video card cooler I just HAD to get.)
Processor: Intel Core Duo 2 E8400 @ 3.0GHz
RAM: G.Skill 4GB (2 x 2GB) DDR2-SDRAM 800 (PS2-6400)
Video card: GeForce 9800 GT. Video is currently set up as DVI to DVI.
Monitor: Westinghouse 47" 1080p LCD Monitor LVM-47W1
Hard drive: Toshiba MK1649GSY 160GB @ 7200 RPM.
Optical drive: ATAPI BD O DH4O3S. It's the replacement Blu-Ray drive that was in my old HP Entertainment computer.
PSU: Raidmax 630W. I only got it b/c it's modular & game w/a $40 rebate (that I never got, of course).
TV tuner: Hauppauge Win-TV-HVR-850
Wireless card: Netgear WNA1100
Put it all together...

A very plain setup for a very plain person.
Currently using Microsoft Remote Keyboard, model 1044. I hate this thing ever-so-very much. What I really want is a wireless keyboard w/backlit keys, so any suggestions there would be greatly appreciated.
