as far as my actual spec goes, i'm fairly pleased with it...
A64 4000+ @ 2.6GHz (cooled with an Artic Freezer 64 Pro)
2GB G.Skill ZX
7800GT @ stock
DFI LanParty SLI-D motherboard
74GB Raptor
120GB Seagate Barracuda
580w Hiper Type-R PSU
All in an Antec Sonata I Case
outside the box i've got
Logitech X-530 5.1 Speakers
Logitech Ultra X Keyboard
Logitech MX510 Mouse
Logitech Quickcam Communicate Webcam
Logitech Dual Anologue RumblePad 2
(lots of Logitech

)
and two monitors, a 15" LG Electronics (TFTLCD MNT) and a 15" Philips 150c4
out of that list, i want a better PSU... i've gone through two Hiper Type-R's and haven't been pleased with the build quality on either (i built my mates PC with the same PSU and his is good though, so i guess i've just had bad luck). Got a Seasonic 600W in mind...
replace the two monitors with one Samsung SM-930BF.
better cooling:
replace the stock case fan with an AKASA Ultra Quiet fan
change the stock cooler on the 7800GT to a Zalman VF700
other than minor improvements like that (okay new monitors isn't really minor)... i plan on getting a second 7800GT when the time is right. and a Lightscribe drive.
