Here's my setup:
TV: Panasonic P50V10
- 50" plasma with THX certification for enjoying movies
Case: Antec "Fusion Remote Max"
- big enough to fit two full-size graphic cards
PSU: Seasonic X-650
- more than 90% efficiency so its fan doesn't spin while watching a movie or listening to soft music
- fully modular for a well ventilated case
GPU: XFX Radeon HD 5850 Black Edition
- HDMI output and powerful enough to play modern games in 1080p
- Integrated HD audio controller
- XFX because they provide life time warranty and a nice packaging
CPU: AMD Phenom II X4 965 Black Edition
CPU cooling: Corsair Cooling Hydro Series H50
- liquid based system for silent and efficient cooling
- no increase in noise when the CPU is running at 100% (while gaming)
HDD: Western Digital 1,5TB Caviar Green
Keyboard: Microsoft 6000
- bluetooth, slim and short
- numpad is detached and it can be used as an additional remote
Game controllers: 2 Logitech Cordless Action PS3 Controllers
Software:
- 64 bit Windows 7
- XBMC for movies
- Winamp for music (has nicer visualizations then XBMC)
