GPU: Gigabyte GTX 660 OC 2GB GDDR5 Dual DVI HDMI DisplayPort PCI-E Graphics Card
Motherboard: Gigabyte GA-Z77-DS3H Socket 1155 VGA DVI HDMI 7.1 Channel Audio ATX Motherboard
RAM: Corsair 8GB DDR3 1600MHz XMS3 Memory
HDD: Seagate 2TB Barracuda Internal Hard Drive

CASE & PSU: Cooler Master Storm Enforcer Case with Coolermaster 650W GX PSU
I am buying these parts of ebuyer.com.
can anyone check if the motherboard will be compatible thanks.
one more thing I want to know that, do I need to have a good case with fans as well as a good PSU? because the case and PSU cost ￡110 a bit expansive..
