The above replies do make sense, and they certainly offer good advice, but having said that, I'd just like to encourage you to be confident in your own choices. You didn't make any mistakes, and all the parts you've listed are of high quality and great performance. I've seen so many posts asking for opinions and critiques on builds, and while there's nothing wrong with asking those questions, especially if it's your first time, just keep in mind that you could get a dozen differing opinions and responses, telling you to go in a dozen different directions. Ultimately, it's you who knows what you need and what you want, and it's you who has to live with the result! So don't be afraid to ignore anything we tell you if you think you have a better idea... And if you do end up making a mistake, it won't be anything worse than a good learning experience! Now... I'll get down off my soapbox and throw in my two cents - great choice on the power supply. The Antec Truepower series is awesome. I've been using a 650 watt TP Trio for two years now, and it's still running strong. There... I'm done.
You will probably need a CPU power cable extension because of the bottom mounted PSU in the Antec 900 case.
Depends on the PSU and motherboard. I had no problem at all getting to the power plug at the top of the motherboard. Either my PSU has long cables or that is mostly a problem with really cheap PSUs designed for business desktops.
The advantage of the bottom mounted PSU is you dont have all the extra cables dangling down in the way. They sit at the bottom of the case out of the way. Makes a big difference if you dont get a modular PSU.
