Phanteks PH-XT523V1_DBK01 XT VIEW D-RGB Black Tempered Glass Steel E-ATX Mid Tower Desktop Chassis

This is an outstanding case, had no deal-breakers for me at all. Great quality and had a lot of life improvements in it that you don't see in other cases.
One thing I was really happy about was being able to remove the docking-bay for the hard-drives in the back, and even when you put it back there is plenty of space for PSU and it's cables (my last case had this problem where it was too close to the PSU).

There was one small problem though but it was an easy fix, and that was that the two side mounted fans might be pointing the wrong way?
This might not be a problem if you add some fans to the top that are intake, but if they're all exhaust like how it was when I got it, then it won't have any airflow going through it. Not sure if this was a mistake but nothing too big and easy to fix.

Excellent case, plenty of room for components and the amount of thought Phanteks puts into their designs is clear. Build quality is hands-down the best of any case I've owned, and it just looks amazing. It could do with a little more space behind the motherboard, but that's really just nitpicking.
