Late to the party, as usual
I know youâve seen my other post, but will repeat it just in case; donât go AIO unless you need to.
Do you need to?
You could get more or less the same cooling for less money (air cooler) and fit it all in a much smaller case.
(bonus? You wonât have your heat exchanger blowing all the heat inside your PC; still canât fathom how folks are O.K. with that, itâs beyond me)
(oh, extra bonus; an air cooler wonât leak on you, wonât lose some of its performance after some time [happens with AIOs])
Now, easily movable with E-ATX, cooling for a 16core, a GPU plus other cards, drives, fans, cables and accessories is not exactly easy. How strong are you? ^^
If you need it moveable as in hand carried, find a test bench. The good ones are both sturdy and cube-y enough to accommodate.
If by moveable you mean on wheels and too heavy to lift, start focusing on what case is best for airflow plus fitting what you need.
(which by the way, you havenât specified, not in the slightest)
In general then;
Best cases (and i mean best, way above the pack) for air cooling, in order of size:

(same brand, yeah; not a coincidence)
Best cases for AIOs, whatever allows you to have the AIO blowing outside your PC, while still being fed with sufficient air from the front. Speaking of which, the CLC you chose isnât designed for TR4 sockets⌠the plate size alone guarantees craptastic cooling compared to what i linked. Food for thought. Who suggested thisâŚ?
The above after some seriously, seriously long time spent on the subject of âcoolingâ; and after having parted with some serious amounts of money, because âindependentâ testing = knowledge + you.
As the Brits say, you want something done⌠do it yourself ^^
Go air, or go straight to custom water cooling loops. AIOs⌠only when forced to; you donât sound forced to me
Added some extra info, apologies for the multiple edits.
