So I was making my usual rounds through the thrift store when I came across a $7 computer. I didn't know what was in it but it did have a DVD drive and a Lite-on CD-burner so I figured the drives alone were worth $7 so I bought it and took it home. I didn't exactly strike gold when I opened it up to find a Celeron 800 processor but it did have a nice ASUS board and it was a socket 370 so I could swap it with a P3 pretty easily. And it booted too. Now the 20GB IBM deathstar drive was dead (if anybody remembers those horrible drives) and the video card was an old Elsa so I was about to pull the drives and dump the rest in to the donation bin before i came up with an idea. I got on ebay and found a 1.4ghz Pentium III (Tualatin) for $6. I bought it and snagged a 60GB WD hard drive for $10 as well. I received the parts and put it together. I installed windows xp and it runs super smooth. At this point I am trying to decide what is a reasonable amount to spend on a video card. I'm into this system $23 and I would like to keep it under $35 total. Any suggestions on what card would go best with this build? And at what point would you stop spending money on such a computer?
