Old Desktop... Sell? Trash?

[mgobluefb]

I built a PC back in 2001 and have been making upgrades ever since. Now that I have a new laptop, I really don't need the PC anymore. The PC works great except for it randomly restarts once in while (not sure what the problem is, vid card maybe, RAM maybe). I could probably fix that problem pretty cheaply. I can't figure out what to do because it's essentially a very solid working system, but after looking at eBay prices, it seems to have no $$$ value. Here are the specs...

VIA Socket A motherboard
AMD Athlon CP 2100+ 1.73 GHz
512 MB RAM
30GB HD
80GB HD
SiS 315 video card
Network card
Sound card
CD-RW Drive
Floppy drive
TV Tuner card
The case is a mess

What should I do with this system? Should I sell it as a whole or should I sell it part by part? Should I even sell it at all?
