Build a PC

[NiX]

Based on PC Express and PC Hub prices
Budget: Maybe P20,000.00 before monitor and accessories
Purpose: Every day use and light gaming

CPU: Intel Core i3-2120 (3.3G) 3mb ------------------------------------- P5,300.00
CPU Cooler: ???
Motherboard: Asrock H61M-DGS H61 VSL or Asrock H67M H67 ------ P2,400.00 (or P3,9995.00) --> No idea if this brand is any good. If not, please recommend similar ones.
Vid Card: Palit GT220 1GB DDR3 128bit HDMI (or Palit GT430) ------- P1,950.00 (or P2,450.00) --> How necessary is a vid card if the mobo already has some graphics capabilities?
RAM: Corsair Vengeance 8GB (2 x 4GB) DDR3-1600 Memory --------- P3,110.00
HDD: Seagate 500gb 7200.12rpm 16mb sata --------------------------- P3495.00
PSU: No idea.
Case: Emaxx Rebel -------------------------------------------------------- P1300.00 --> any other recommendations? Although I still have the old one. How do I know if it'll still do?

Btw, I don't plan to overclock or anything like that. Will probably use it till it breaks, too.

Thanks for all the help so far. I think I'm almost there.
