Pros: Solid, great airflow, lots of space
Cons: Could have done with more clearance above the motherboard, and removable 5.25" bays
I have built my newest rig with this case but had to make some modifications in order to get it all to fit neatly.
Firstly, the clearance above the motherboard to the top of the case is 85mm almost exactly. Whilst I thought I could fit a 60mm radiator with 25mm push fans in there, it was so tight to the motherboard that I could not. So I decided to mount my rad on the top of the case itself and use a dremel to cut out some holes for the radiator fittings. This also allowed me to run a full push pull set up on the rad as well for increased cooling capability.
My next gripe was the 5.25" drive bays. This is 2017, and whilst this case has been around for a while... So have fast USB optical drives. Huge big 5.25" bays just seem like a waste of space. Unfortunately the bays in the 750D are riveted and actually part of the chassis itself. However if you are handy cutting some metal and drilling out some rivets like I did then you can remove the bays to free up a whole load of space.
I do like the sideways mounted SSD clips in the front of the case, however would have liked it if there was a cross brace style bit of metal joining the front of the case to the motherboard tray here as well which would have made fixing items like a res/pump a lot easier.
All in all, with a few modifications, this case can be the foundation of an absolute monster build/project. It has great airflow and potential for large custom watercooling set ups with multiple radiators, providing you stay with in the constraints of the available space (or go external like I did). This case gets my approval!
