Get a Palit HD4850 for 9.2k
hmm for mobo you can try a XFX 630i @3.2k
use the RAM u have right now.....no need to get new.
Get a Western Digit Caviar 640GB for 3.6k
Keep the case u have.....its better than Bijli
CM 500W will be a nice PSU......stick to it.

If u want a CPU then get a E7200 for 5.4k.
