The glass side panel is amazing, the lighting is cool too.
My only really gripe is the poor airflow in the front and top. Oh and only having 1 SSD tray behiond the motherboard. I would have liked a second, as my other SSD is just wedged in the bottom behind the PSU out the way.

But the tempered glass is 100% the best feature for sure.
