Put in a 2080ti or a 1080ti for the previous gen One an a 9900K in a Dr Zaber case and water cool them I would really like to see that.
You’ll need a DC-DC set up and a custom one to boot, and an external water loop.
Not to mention that even building an air cooled SFF build is hard, SFF components are rare in many countries and often require you to import it yourself which adds a big premium in the form of import fees, you also need an SFX PSU for that case and one of the smaller ones to boot as well as likely do your own custom sized cables to actually fit things in.
