Well, I know Hitachi makes TVs, Batteries, and so on, so I'd expect WD, which is a company that makes HDDs and nothing else to be much more reliable... Plus I don't like the name, sounds cheap and chinese xD I think 600 Watts would do, yes. I mean, heck, those 1kW PSUs can run dual GTX780s in SLI, how can't half of that (500 Watts) run at least one? And the 760 is much less power hungry than the 780... So 600 should be enough and future-proof.
Well, that makes me change my mind. I have a 320 gb Hitachi from an old HP that a recently formatted to make compatible with my mac (had about 36 partions). I was thinking that maybe 600w would be appropriate.
=========== @bmc Here's a chart I found on HDD reliability: [Clickety Click] It seems like very chart suggests that Seagates are the least reliable drives, although I wouldn't agree on Hitachi being the most reliable. As for the PSU, 750W should be more than enough
It looks rather nice; I can only comment on the PSU and the HDD though... I have a Corsair GX600 PSU, which is absolutely AWESOME! Heavy, well-built, and it's nearly silent. Not sure if this Builder series one you chose is any different, but my experience with Corsair is fantastic... As for the HDD; Well, I've had some bad experiences with Seagate... If I were you, I'd get an equivalent Western Digital - If the price difference allowed it. Hope this helps
