I use most of my outdated parts for overclocking/abuse except if they are not suitable to be sold. Currently own two old PCs, Athlon 1600+/GF2Ti/512RAM/40HDD I use for wireless router and an OCd machine: Athlon2000+ w/unlocked 26kb of L2 cache, clocked @ 12.5*185~2300mhz/GF6600GT@590/1150mhz
EPoX 8RDA6+
2*1GB SuperT Memory @444mhz
3 Seagate internal hard drives,total 440GB plus an extarnal FreeAgent 1.5TB
Plextor DVD Recorder
self customized case and cooling
I use this machine for file server now, used to play games on it, but by today's standards, its ridiculously slow for that purpose, even when it comes to non3D load, my primary computer, a DELL laptop puts it to shame and makes me feel really bad, I dont even want to remember what a beast that machine was at the time of purchase (and, of course, how much it costed)
