Touching Up on my Gaming Rig

[Macss]

CPU: FX-6300
Motherboard: GA-990FXA-UD3 Gigabyte
Ram: Team Vulcan 8GB (2 x 4GB)
Hard Drive: WD Blue 1 TB WD10EZEX
GPU: MSI Radeon R9 270
PSU: XFX Core Edition PRO650W

How does it look? I've been working on the parts for a while now and trying to keep my budget of about 700. Any tips would be great!

Looks pretty good to me. For cases, I usually prefer a corsair, nzxt or fractal design but that is more of a personal choice (not sure how good the airflow/heat is for the Rosewill cases though).
