Soldered memory and no x16 PCIe slot on a desktop are interesting choices. Not sure who the target market is. Seems like the interconnect between boards is also pretty slow compared to Nvidia Digits or even thunderbolt 5.
It's got a rtx 4070 laptop chip equivalent on chip, so most are not going to need more GPU or anything else that needs a x16 PCIe. Looks pretty nice for a small PC that's quiet, energy efficient, and don't flinch if you try to run something 3D intensive.
