PC build exclusively for Rocket League at 1080p

My friend wants to build a computer to play Rocket League at max settings and nothing more.

What he needs:
CPU
Mobo
RAM
Hard drive
GPU
Case
PSU
Optical Drive
OS
Wireless Network Adapter
Case fan?

Will be using TV for monitor. No mention of keyboard/mouse... be he can figure that out, need be. I should add that he's never overclocked and has no intentions of doing so... especially for a game like Rocket League.

Thank you!
