So I recently built and assembled my first desktop

Motherboard
Asus M4A88TD-V EVO USB3 Motherboard

CPU
AMD Phenom II X4 955 Black Edition Quad Core Processor

RAM
Corsair 4GB DDR3 RAM x4

Video Card
EVGA GeForce GTX 550 Ti

Hard Drive
Seagate Barracuda 1TB

DVD Burner
ASUS DRW-24B1ST DVD Burner

Case
Thermaltake V3 Black Edition Mid Tower Case

Power Supply
Cooler Master GX Series 650W


Once the DVD burner arrives from UPS today, I'll be able to download Windows 7 and all the other stuff I need on there.


My question is, is there anything else I should be buying for my computer to 100% work? I already have the mouse, keyboard, monitor, and I'm not worrying about speakers atm. I know I still need a wireless adapter, but do I need anything else??


Also, with the wireless adapter I'm not really sure what to look for. Should I be getting a -G or -N adapter? PCI or PCI express? Other than the adapter, do I need anything else to get internet for my computer (we already have a router)?

Go with a USB WiFi adapter like this:
D-Link Wireless
