Tough build, 360mm radiator is going to make it not as small as you would like I imagine. Still have to have a CPU cooler as well. Air or water?

BIOS flashing may be inevitable if you want the latest CPUs. Both Intel and AMD released chips without a new chipset. Certainly will pick a board that has CPU-less flashback though.

A shame caselabs isn't around any longer. Not actually finding any of the smaller cases in stock anywhere. I think the trend for SFF is to make 240mm radiator the base size, usually top and bottom with the computer sandwiched between them.

If you can find a Cooler Master HAF Stacker, that would probably be the easiest I can think of. I looked around for other low volume chassis, they just don't support a 360mm radiator. Other option would be to look at Micro ATX towers that are small.

Keep in mind you will want a beefy power supply to go with a 3090, 850W is the bare minimum recommended.

I had actually looked at that a little. Similar problems, the market for MicroATX cases with 360mm radiator support basically never existed.

This is the nicest one out there I could find. (Also a lack of good MicroATX motherboards, so sticking with Mini-ITX)

Not exactly low volume, but it is shorter than average.

Why the need for SFF?
Is there a particular dimension that is troublesome for your space?
Do you have a budget?

With the need to fit a 360 radiator for the Kingpin, there can be nothing really small.
You might look at the lian li PC-O11:

Remember that you also need a cooler for whatever processor you install.

there is no place to put a mid tower in my tv room. I'd have to modify the wall unit or just put it on the ground in the walkway but sideways. undesirable

Can you supply a photo of the room?
Perhaps there are some other solutions.
Lian li makes a very good PC-07S case that is designed for media rooms.
It should be able to handle a 360 radiator and a 3090 that is 303mm long.
The really interesting thing is that it is designed to be wall mounted.
