My first PC was a IBM 600x Pentium 3 based laptop with 256mb of ram and 20GB HDD. It still works and i use it as a "server" for my printer. Next i got a custom build PC with Intel Core 2 Duo clocked at 2.2ghz 4gb of ram and 9500gt (512mb version) i sold it to a friend and it still works perfectly. And you can check my current build in my profile.
