FYI: Building in this case is a terrible experience. Flimsy panels, acrylic side panel, restrictive airflow, low build quality. Spend $20-$30 more.

The CM Elite 302 is a much better deal for $10 more https://www.newegg.com/p/N82E1681...6811119463

No problems with it. Feels cheap? It's this price for a reason. Airflow? Remove the magnetic filter.

I have this case, I was just building something conservative at the time and it's met my needs over the last several years. (I turn my PC on like once every 2 months). I enjoyed that I can relocate the usb slots and the power button, I also have no idea where the magnetic things are!
