my cousin built my first computer (NF7-S, XP2100, 512Mb PC2700, TI4800 128Mb) and i re-built that into a windowed case about a year ago. Last December i sold it for £450. Built my new one from scratch (see signature) and thats how i because so interested in hardware.
Since then i have built my parents (IC7-G, 2.8c, 512Mb, 9600XT), rebuilt my sisters into a new case (XP2000, 256Mb PC2100, 64Mb internal Ge Force 2 MX), Built my nans (KV7, 2600+, 256Mb PC3500, FX5200), a couple computers for mates, and yesterday i delivered the latest build (A7N8X-E Deluxe, 3200+, 1Gb PC3200, 9800 Pro) to a friend.
There ya go.
