i'm only gonna post my two main systems.

just built a new comp:

Shuttle SG31G2 barebones
Intel Core 2 Quad Q6600 Kentsfield 2.4GHz
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066
Western Digital Raptor WD740ADFD 74GB 10000 RPM SATA 1.5Gb/s
LITE-ON 20X DVD±R DVD Burner Black SATA Model iHAS120-04
PNY Nvidia 7600GS PCI-E (older card)
500GB Music drive via SATA
500GB HD video drive via USB
WD external "book" 500GB TV drive
WD external "book" 1TB Movie drive

then my other computer's pretty old, but a mini server.
ASRock mobo (don't remember model)
2.4ghz AthlonXP
1gb pc2100
ATI 9800
about 8 hard drives totaling ~1.5tb.
this computer's actually down right now, (won't power on, possibly psu), when it's fixed, I'll move the externals from the shuttle to this computer, and it'll be ~3.5tb.

kvm switched, and eventually i'll run vnc to control the mini server. dual monitors as well, w/ a hd lcd tv next to them :)
