wow, that is a lot of money for a pc. I do have some questions on the your choices bjammzz... is a radeon 9500 pro really worth $229? Isn't a Radeon 9600XT cheaper and performs better? Plus, it comes with a voucher for Half-life 2, so that's like a $40 gift certificate. Also, if you plan on using an SATA hd later, you need to make sure that your PSU has the connectors for it right?
About the HDs, I've always liked Seagate, they seem to be quieter than Maxtor drives. Buying Seagate doesn't mean you won't get a defective drive though, I think all HD companies don't test as much for defects so they can sell the HDs at much lower prices. I bought a Maxtor 120gb two months ago and it started making clicking noises so I will have to get it replaced soon. By the way, if a company offers a 3-year warranty for an extra fee, I suggest you get it.
