ADDITIONAL COMMENTS: Looking for something that will last a while and is upgradeable, which is why I'm starting with an i7. Not planning to overclock anytime soon. Also, limited on space, so I need the smaller case.
Here's what I've got so far:
Antec Sonata III 500 Black 0.8mm cold rolled steel ATX Mid Tower Computer Case 500W Power Supply
SAPPHIRE 100277L Radeon HD 4770 512MB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card
My DVD-R is an 8X HP (a few years old) so I either need an IDE connection or need to replace with new SATA. I figured I'd eventually do this, but I'm trying to watch my spending now. I'm currently running XP, but I had planned to move to either Vista x64 or Windows 7 RC x64 (which I like a lot better). My current computer just isn't fast enough and rather than upgrading old/failing components, it makes more sense to build new.
Any help or advice you can provide would be appreciated.
Your build looks good, I would also avoid the ECS motherboard, the Asus P6T SE is a great board specs-wise, it is one of the cheaper x58 boards out there and supports a full 12gb of ram in triple channel.
