Best CPU for ASRock DeskMini STX H110 board? SKL? KBL? 65W max?

So, I own an ASRock DeskMini STX rig. It's basically a mini-PC, that takes a stock (no OC) Skylake desktop CPU (65W max), and thus is much faster than a NUC that has a soldered U-series Skylake low-powered CPU. It also takes M.2 PCI-E (only) SSDs, and a couple of 2.5" HDDs / SSDs, and DDR4 SO-DIMMs. It has an H110 chipset, and comes with an M.2 Intel Wifi card in the kit.

Enough about that.

Currently, there is no notice about Kaby Lake compatibility with this mobo. I hope that there eventually will be.

Assuming that this happens, then what would be the best choice for a CPU for this rig?

It will take an i7-6700 (non-K), that's the highest that it takes right now.

But if it will take KBL, I was wondering about the i3-7350K. I know that it wouldn't be able to overclock, being in an H110 board, but that already has a high base clock, and benchmarks suggest that it is as fast as an i5-6400. However, I like high single-threaded performance, so I would probably choose the i3 over the slower-clocked i5.

I think some of that comes down to what TDP Intel specifies for the i3-7350K, because if it is over 65W, then the mobo may reject it, for safety reasons. (Which, at stock speeds, given that it cannot be overclocked in a H110 board, might be a mistake, as they specify a higher TDP for the "K" CPUs, assuming that they are going to be overclocked.)

I like the idea. IF the i3 7350k comes in at 61 watts..

Core i3-7350K 2/4 4.0 GHz 4.2 GHz 4 MB 61W? LGA 1151 $177 (Pre-Order)

The other idea, if I want to stick to inexpensive, is to just pop an i3-6100 in there, for the lowest-cost four-thread and HD530-capable CPU.

But since there is no GPU PCI-E slot, the iGPU specs are important. That's one other reason I hope KBL compatibility comes to that board.

Usage would be basic desktop tasks, web browsing, video-watching (YouTube) @ 4K60, maybe some DC if I get a chip that does AVX/AVX2.

Sounds good to me! Says BIOS versions after P1.40 will support KBL. (Must be what that mysteriously-labeled "microcode update" was for. :) Funny how they didn't mention KBL or 7th-gen Core anywhere in the update notes. Sneaky ASRock...)
