The computer is a Systemax and has 512mb memory and an AMD athlon XP processor, it's in really good shape. Other than that, I don't know too much about it. I'm not the most knowledgeable about computers... I guess I'll have to learn!
And I went with everyone's advice and got a CRT monitor. I was looking at some LCDs but they just didn't seem right. I also have a usb keyboard and mouse that I found that should work with it.
I'm still waiting on the monitor to be delivered, but I can't wait to put it all together!
Thanks again for all the help, I really appreciate it! I'll post more information as I learn more.
