Hi,

I'm making a build for a computer (around 1000 euros budget) but since I'm new, I figured I could use some help
This is what I have so far:
CPU: Intel i5-3570k
GPU: GIGABYTE GV-N670OC-2GD GeForce GTX 670 2GB 256-bit GDDR5 PCI
RAM: 8GB Kingston Value SODIMM DDR3-1600
Motherboard: Asrock Z77 Extreme6 - Socket 1155 - ATX
PSU: Antec BP550 Plus 550W Continuous Power ATX12V V2.2 80 PLUS Certified Modular Active PFC Power Supply
Case: Cooler Master Storm Trooper
Network Card: ???
SSD: SanDisk ReadyCache SDSSDRC-032G-G26 2.5" 32GB SATA III
HDD: WD Blue WD5000LPVX 500 GB
Cooling: Noctua DH-14

If you find anything wrong/missing with this build, please tell me.
Sorry if this is in the wrong place by the way, I wasn't sure what to put it in.

Thanks in advance!
