I'm sick of these Anti-Windows fanboys.. I have never had a single issue with windows, I've used Linux, but all the configurations just lead to the same performance of Windows.. I agree that Vista is going to suck hard. Get this, before Vista has even been released, tests have found over 40 Critical Security flaws.. like catastrophic.. gg windows.. but on the topic of your computer Asinth. I'd say that an Athlon 64 bit Processor, a Radeon Video Card with 256 MB video memory, at least 1 Gb of RAM (2 Gb is overkill, unless your on AIM, Downloading pr0n, and using a high end graphics program while playing HL2) NIC cards are cheap, any kind will do, as for the MOBO, just get something that can handle the Processor and some decent RAM. Dont be intimidated by building a computer. The only thing that is easy to screw up is applying quicksilver (heatsink Compound) and putting the heat sink on. Be gentle but use force for the heatsink, and apply compound liberally but not too much. If all else fails, read the manuals for all of your parts, they give helpful information, like installation tips, and possible hazards when working with expensive parts. On the subject of a Case; you can turn a boring case into something sweet, with some spray paint, a skillsaw, some plexi-glass, and some fancy modlights, and fans. Oh Oh, make sure to get some fans to put in the case, to help cool your processor, but remember you need intake and exhaust (in and out) otherwise you are just blowing around warm air. Hope I could help
