Hey folks, About to either completely overhaul my old Dell Dimension 8300, or just plain build a new one from scratch. Any advice on a decent but cost-effective build? Any suggestions on parts that worked better than you expected or parts to avoid? Not trying to build anything completely top of the line, but my current system doesn't cut it anymore. I'm decent with replacing parts and the like, but I'm trying to avoid any overclocking that would require additional cooling systems, etc. since its a little outside my comfort zone (plus I don't want to screw up and fry something since I'm trying to save money!). Thanks!
