Just wondering how much this is worth?

Dell Vostro 200 Mini Tower system (black)
7.1 sound, VGA, USB, multi card reader, all built in
Radio X1300 Passive PCI Express GFX
2gb DDR2 Ram (2x 1gb)
320GB SATA Drive
DVDRW (Optariac?) SATA
Vista Home basic / and Dell Recovery partition
Intel Core2Duo 2ghz

with Dell keyboard (multimedia) and mouse, and some warranty assuming it's transferable?

Thanks

Josh
