PC Gamer periodically publishes a 'build your own PC' guide; I've found this to be a really good place to start. www.tomshardware.com is also very informative, and the forums there are a great resource for PC builders of any skill level. Just remember to go slowly and keep yourself grounded (mentally and electricly)...it's hard to really screw up, so long as you don't force anything during the building process.
Thanks everyone for the advice. Building a new computer will definately fit my needs. Also, I see it as a cheaper option in the future because i like to keep up with technology (I guess it's better to upgrade than trash a computer and start all over again).
Anyway, now that I've decided to build one, I was wondering if anyone knows of some good sites, books, etc. that are really informative when it comes to building the computer, details of computer parts, and anything else I should know. It's near impossible to find one really good source for info like that. Plus, I am sure there are others that want that same info, too.
