The chassis appears to be the same from the previous B660 version, but ASRock added a few new upgrades for the B760 motherboard, including support for up to an i9-13900 processor, a PCIe 5.0 x4 M.2 interface, a USB-C 3.2X2 connector and 2.5 Gbps ethernet.https://www.notebookcheck.net/ASRock-announces-DeskMini-B760-mini-PC-with-support-for-up-to-an-Intel-i9-13900.748753.0.html
ASRock sadly ended their DeskMeet line with room for a short dGPU and it's too bad there isn't room for even a short dGPU in the DeskMini, given Intel's base integrated graphics are still lousy.
An AMD version will allow the use of upcoming APU models with better RDNA3 graphics hopefully.
No dGPU slot? Sounds like a downgrade to even the previous AMD option. Not worth the upgrade.
