Case, CoolerMaster HAF 932, Full tower ATX case. Plenty room for large vid cards, multiple fans with room for water cooling in the future. Its an all metal case. Bit pricey but its been around awhile. Should be able to get a good price. I own 2. Will use them till ATX form factor is no more. Newegg had them for $139. Search around.
I would suggest an Nvidia based GPU card. I know peeps that had trouble with ATI/AMD Radeons?????????????????????
If you are not over clocking, the stock cpu fan will be fine. Later you can consider an aftermarket cooler if necessary.
Consider a larger PSU, 750W minimum. Maybe 850W, a good PSU will last many builds into future. I have read where they operate best at 80% of capacity, leaves a little overhead I guess.
Drop the Blu ray, add it later. Unless your gonna use a semi large screen HDTV to view movies. Apply dollars another way.
Remember, its about the vid card, the ram and a cpu that can push it. Then select the mobo. If you gonna use a spin drive, get one that has some rpms. The Western Digital Raptors spin 10,000 rpm, better performance.
Also be aware of software drivers, ie: chipset drivers, the bios of mobo, If you buy a slightly older mobo, you might need to get the latest bios for it, same with the mobos drivers. They will give you a disc with the stuff for it, but these things are always updated. You might as well start off with the most current drivers for mobo. ie; you would want to update the bios before you install the OS. read up. Same thing with the OS, get all the MS updates in before you start installing the software you want to use, as in the games, AH.
Theres a lot of crap to involve yourself with, but getting your ducks in a row will save you headaches and troubleshooting.............
