I would think that building a PC with that old case might be tricky. Man manufacturers make the cases so that they are difficult to upgrade so that you have to buy a new comp instead of upgrading that one....stupid marketing ploys
I think it might be tough to salvage that case and power supply is most likely not powerful enough for today's hardware. As another marketing ploy, computer manufacturers make it so that the power supply just supports the devices in the computer so you can't upgrade. What I'd recommend doing is getting a case of www.newegg.com
. You can get a case and power supply for $60 bucks, which isn't bad. I'd be happy to help you customize a PC on here. How much are you spending and what will you be doing with it (gaming, video editing, etc.)? For one last thing, a great website to show you how to build is www.pcmech.com/byopc
. I used it and it is very thorough. GOOD LUCK!
