It has been done and sold but it's a niche thing because Intel doesn't allow this "hackery" out of wanted specs to large brands that sell in the "western" lands. In China... they got it.
All these talks from Intel how one needs a new motherboard are a load of crap, it all runs even on Z170 even with DDR3. The dies are "universal" and as such contain parts that are not used on desktop in products but are used elsewhere where these dies end up, mobile, etc.
Of course having adequate power delivery is another thing but that goes for any motherboard and CPU combination.
There are some "updated" or hacked UEFIs that add support for 9000 series on lower boards with a flash, you may also need to mask pins.
9900K OC eats a crap ton of power. 170W stock, 200W all core and around 250W OC and 100C on custom loop.
It will be interesting to see how 3900X and 3950X do in terms of power and temperatures beside the expected performance.
Would definitely not bother investing in any Intel platform based on Core, period. Be it for home use or business use.
