Right, I've been doing some comparing and reading reviews and this is what I came up with.
Graphics:
http://www.newegg.com/Product/Produc...82E16814130572 - $130 - Cheaper than the Sapphire Radeon HD 5770, but would there be a notable performance difference? It's got a 5/5 average rating.
Power:
http://www.newegg.com/Product/Produc...-028-_-Product - $35 - seems to be quite the bang for the buck
CPU & Motherboard:
http://www.newegg.com/Product/ComboD...t=Combo.500536 - $182 - Motherboard is quite a bit pricier, but I don't trust the cheaper one. Think it's worth the money?
Case:
http://www.newegg.com/Product/Produc...82E16811146059 - $40 - Cheaper one seems a bit too basic.
Memory:
http://www.newegg.com/Product/Produc...-227-_-Product - $90 - The OCZ one has very bad reviews.
Storage:
http://www.newegg.com/Product/Produc...Spinpoint%20F3 - $75 - cheaper ones seem to have quite a high failure rate.
Optical drive:
http://www.newegg.com/Product/Produc...ung%20SH-S223C - &20 - seems to do the job although rather high failure rates. The only thing I'll probably ever use it for is installing WoW expansions, lol. Anyone have any better recommendations or will this do the job?
OS: Windows 7 Home Premium OEM - $105 - Don't like Windows but it's not like I've got much choice!
Display: ???
Keyboard: ???
Total: $677 + display + keyboard
Not sure if I'll need an audio card. Not sure about which display and keyboard to go with either - I doubt an iMac can be used as an external screen, and the Apple keyboard won't play nice with Windows 7 either.
Thoughts/ideas?
