To avoid being negligent, here are some photos of my system. I don't have a good flash for my camera (just the built in flash), so the photos could certainly be better.
Here's an overview showing the TV and cabinets. The TV is a Mitsubishi WD-65835 - the current Diamond Series DLP. The speakers in this picture are B&W Matrix 802 Series 3 left/right, B&W Matrix HTM center, and Velodyne HGS-18 subwoofer. There's a Crestron ST-1700C controller and wireless keyboard for my HTPC on the coffee table. My dad made the chest on the left which looks like an older piece of furniture, but uses ball bearing drawer slides and holds my DVD collection, owner's manuals, extra cables, etc.
The left upper cabinet contains an XBox 360 Elite, PS3, JVC HMDH40000U D-VHS VCR, Denon DVD-3930CI, and Denon AVP-A1HDCI. I'm seriously considering getting Middle Atlantic custom shelves for the XBox, PS3, VCR, and Oppo BDP-83 (which will replace the 3930CI) and rack mounting those items as I've come to REALLY like having stuff rack mounted because it makes it easier to work on cabling, and the components don't shift when you push buttons or insert/remove media.
The left lower cabinet contains my HTPC (and the external box for my sound card), Panamax MAX 5300 power strip, Crestron AV2 controller, Crestron CNMK mouse/keyboard controller (allows the Crestron equipment to control the PC), and a HomeVision controller:
The right upper cabinet contains my turntable (Basis 2001, Graham tonearm, Benz Ruby 2 cartridge), a Parasound Zhd 5x1 HDMI swither, 3 DirecTV HR21 Pro's (each with an AM21 OTA tuner box), and an older DirecTV HR10-250 (HD Tivo):
The right lower cabinet contains a Krell KPA phono preamp, another Panamax MAX 5300 power strip, 2 Crestron ST-COM modules, a Crestron ST-CS current sensor module, and the power supply for the Krell phono preamp. You can also see the backside of a Dell gigabit network switch above the Panamax, which is mounted to the rear of the rack:
The middle cabinet holds the TV, 2 Krell KAV-250a/3 power amps (to power the front, side, and rear left/right speakers with 250wpc), and a Krell KAV-250a power amp (bridged to 1000 watts to power the center speaker):
This shows the rest of the room, including the side and rear B&W Matrix 804 speakers. My dad also made the cabinet on the left which holds my LP's, extra cables, etc. Yes, that's a Victrola on the table in the back. The futon will eventually get replaced once I decide what I want to go with.
This obviously isn't a dedicated room like some of the others are so fortunate to have and I don't have acoustic treatments on the walls, but it works out surprisingly well and the system sounds great. We've got blinds we can drop to block the big windows to keep light out when watching movies or if it's too bright during the day.
