While Minisforum is better known for their Mini-PCs, it looks like they're now branching out into MoDT (Mobile on Desktop) Mini-ITX motherboards.
MINISFORUM BD770i – Minisforum
The BD770i has a soldered 8-core Ryzen 7 7745HX and includes a heatsink, and mounting holes for your choice of 120mm fan. It seems fairly well priced at what may be an introductory price of $399.
I'm personally interested in the more powerful 16-core Ryzen 9 7945HX or hopefully 7945HX3D option which should be available soon.
