I'm looking for something that has good airflow, AIO radiator mounting options, I/O ports on the front (I put stuff on top of my computer case so I'm afraid I will break connectors), acryllic/tempered glass side panel (I'm planning to use a fancy mobo this time), allows me to put things on top of the case (arcade stick, controllers, Switch dock, etc) without choking airflow, and doesn't look like ass. Many of these seem to be mutually exclusive to one another.
So I solved my case dilemma in the hackiest way possible. I decided on this case: https://www.newegg.com/petrol-blue-fractal-design-focus-g-atx-mid-tower/p/11-352-073 which has shit front I/O. HOWEVER it also has 5.25" bays, so I'm pairing it with this https://www.newegg.com/p/376-0067-00006 to add proper front I/O to use instead.
With that, I have pulled the trigger on the Mark VI "Blue Blur" computer! This is going to be an interesting one...
