I need to get a new computer and thinking about putting one together myself. I'm studying computer animation and just killed my laptop trying to put a new fan in it. I'm a lifelong mac user, but I'm thinking I may be able to put together a better machine than, say an iMac, for the same price. How hard would this be with no experience or knowledge of hardware (see above story about laptop fan) and not a ton of time? Is it plug-and-play, or is thre soldering and stuff involved? Where would I start?
