Its a great case, and cheaper.
you can then use the money saved from the case towards another graphics card, as the 3650 isn't really ideal.

what resolution do you use?
I chose Sapphire because XFX constantly go faulty and I don't really want to be dealing with faulty parts.
HIS ATI Radeon HD 4870 512MB GDDR5
Good deal for 98 quid !
