I know it's not as fancy as some of your guys' computers, but I'm very proud of mine because I built it for about $800 give or take a bit.
C2D E4500 2.2GHz
EVGA 650i Ultra MB
2GB ADATA DDR2 800 RAM (I have another gig of Samsung, but it makes comp crash once a day)
CoolerMaster 460watt Power supply
Some old Antec case
XFX 8600GT 256MB GDDR3 XXX edition with Zalman fansink
DVD-RW drive not sure how fast
500GB Seagate HDD (replaced what is now my 80GB doorstop)
Gateway HD2200 22" monitor (OMG it has no buttons on the side, just a touchscreen border! Amazing!)
A few accessories
Logitech Driving Force Pro
Homemade shifter (I cut up an Xbox controller, wired the buttons to contacts on my shifter and then plugged it into the computer via USB, all because I wanted a Logitech G25 without paying $300 for it

)
Regular Xbox controller used for Halo and such on PC
Saitek ST290 Pro (got for $4 at thrift store)
Microsoft Wireless Desktop 2000
Many flash drives of various capacities
Printer, scanner, USB hubs, etc...
