230W PSU is a definite NO, that might not even support a low end IGP. There are also many other bits in there that wont work, the DDR3, AM3 board, and the PII 940(AM2+).
Swap the 940 for the 620 or 630, there isnt much of a difference between the PII performance and the Athlon II's performance so the savings are worth it when you are on a tight budget. Get atleast a 500W PSU like the EA500, or the Corsair 550VX. Swap the 500GB caviar blue drive out for a 500GB Samsung F3, its a lot faster. Drop the H50, you can get similar cooling performance from a decent air cooler like the Hyper 212+ for signicantly less.
