Very likely possible. I'll try and reply to @Bombastinator's post later. I'm currently dealing with a summer cold. Although I now remember wanting the P600S because of its better perceived airflow capabilities. I'll have to go to a store that has them both so I can check them out in person. Videos only do so much to help you make a choice.

afaik p600s launched in 2019 & define 7 in 2020
i think you might be thinking define r6 / r5 / s2
 
 

fractal define 7 (not the compact) or their budget "pop XL air" case can fit those

Sorry. TG is tempered glass. I love the looks but would prefer a solid panel. CM is Cooler Master. This is the CM case per that thread. It looks very old design wise but I'm sure it may get the job done.

The P600S grabbed my attention due to the plate tilt tech but how easy it easy to go from smooth and slow to high performance when needed without time to learn a complicated latching mechanism.
 
So I know the front portion of the P600S can handle a 420 mm rad. Is it safe to say buy a 420 mm AIO and have the radiator at the front of the case with 3-4 exhaust fans at the top instead of relying on just a 360 mm AIO at the top?

*doesn’t know what TG is.  Or CM for that matter*
 
As far as 2 fan cases with 5,25” bays there could be a use for such a thing.  HTPC comes to mind.  Have to be low heat production and you need a full half height bay for a lot of blu-ray drives.  A machine that doesn’t produce much heat doesn’t need many fans.

soon the "550W is enough for a single cpu and gpu system" will be invalid
glad i bought an RM850x
