Hi, I recently built a budget gaming pc a few weeks ago, and I am ready to upgrade. Here are the specs. Fx4300@3.8ghz, gt 630 (got it off my friend for 20$, why not), rosewill ranger m micro atx case, gigabyte ga 78 lmt USB 3 motherboard, and a corsair cx430. I am upgrading my gpu to a asus radeon hd 7770 direct cu 2gdd5 and my case right now is pretty bad. I want a nicer larger mid tower, and i'm done with micro atx cases... I am looking at a new case for between 45-65 dollars. I see the coolermaster haf 912, the antec one, nzxt source 210, and i'm fully open to recommendations. Please leave some suggestions, looking for good airflow, and it should look nice and be on amazon.
