No case is perfect, but for me the problem with the Lian Li O11 Dynamic XL, the Fractal Design Define XL7 too, is that they are the modern view of essential drive space, SSD and NVME at 2G or less each. They are from a different planet to the Enthoo Primo, a case with a lot of what I lurve. To me the question would be 'what can I do with the Enthoo Primo.' Fitting an Extreme to the top of the case, I like the sound of that approach.
For me the main weakness of the Enthoo Primo is the positioning of the top panel controls. I switched those around to the front panel 5.25 bays, but the Extreme at the top could allow space top front centre, grill position. I find that thought exciting, more convenient than what I have now.
So, Fenice19 did want to change to a different case. ...
