How to build a gaming computer and what to buy to build it.


I have no experience with building computers so I have no idea what I need or how to build it.
These are the components I've been looking into, please help.

-MSI R7870-2GD5T/OC Radeon HD 7870 GHz Edition 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card
-PNY - 2-Pack 8GB PC3-12800 DDR3 Desktop Memory Kit
ASUS M5A97 LE R2.0 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard with UEFI BIOS
-Black/Red Raidmax BLADE ATX Mid-Tower Computer Case ATX-298WR, 4 x 5.25in Bays, Water Cooling Support, 2 x 120mm Fans, Front USB2.0/Audio
-CORSAIR TX Series CMPSU-650TX 650W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Active PFC Compatible with Core i7 Power Supply & New 4th Gen CPU Certified Haswell Ready
-Seagate - Barracuda 500GB Internal Hard Drive for Desktops


This is all I was looking at... Are these components all I need?. Is there any other parts that'd be better for there price? (I don't want to exceed $600 in costs) thanks a lot, and info would greatly help me.

You forgot the most important, Processor

I'm thinking a CPU would be a nice addition to your parts list
This video (although the parts are outdated) is quite good on how to assemble your computer http://www.youtube.com/watch?v=d_56kyib-Ls
