I built a pretty damned good computer, that im still using, 2 or 3 years back.
MSI motherboard
Intel P4 3.2Ghz Prescott Core
1024Gb DDR400 ram
Creative soundblaster live 24 bit (into 7.1 creative speakers)
74.6Gb WD Raptor (10,000RPM) SATA harddrive (windows XP Pro installed on this drive)
250Gb Maxtor DM10+ (7,200RPM) SATA harddrive, specifically for games and software
200Gb Maxtor DM9+ (7,200RPM) SATA harddrive, specifically for media (pictures, music, videos, webpages (i make alot of em) )
Hercules 128Mb 9800Pro, which burnt out with a few other components when my original PSU burnt out.
Now it has an IceQ Artic Cooling 128Mb 9800 Pro
It has an MSI DVD Rom, and MSI DVD-RW, i cant remember the speeds, but they arent much slower if at all from current production drives. Also has a multicard reader slot
Use a Viewsonic VP121b monitor, its not the biggest but i like having space
Use a Logitech MX550 mouse and wireless chieftec keyboard
The PC is housed in a Chieftec Matrix case in black/grey, it also has a side window, uses antec blue led fans and an Akasa 460 watt PSU, with blue LEDs
It really isnt that much anymore, but when i built it, it was almost very high end.
Still tho, manages to play HL2/CSS, Doom3, Quake4 etc etc fine
