Ok so I've wanted to build a PC for a while and haven't had the time, and before I do I want to fiddle around with one so I get the hang of it, so down the boot sale I picked up this crummy old case. Get it home it has an AMD Athlon 2200 XP inside with 512kb ram and a 80gb hard drive. . Not great. So tell me this, how can I simply improve the system without spending much so I learn about the parts as well as seeing enough improvement to turn it into a workable PC for the misses?
