My mom runs a home daycare center and is a big movie buff, so I decided to make a Multimedia/Browsing CPU for her and the kids. I'm trying to stay under $525. So far it's:
AMD Phenom II X6 1045T CPU
AMD Radeon HD 6570 Video Card
1TB storage (could go down to 500GB to save some $$$ for other parts)
12GB RAM (Memory) (Once again could go down to 8, but the more, the faster this puppy goes)
450W Power Supply (Hopes that's enough, if not I can go up to 500-600W)
With these specs, I think they should be set for 3-4 years before an upgrade is needed.
