## What reviewers say

**Minisforum UM790 Pro** — Two whitelisted outlets reviewed this exact model hands-on: Notebookcheck (Ryzen 9 7940HS / Radeon 780M, July 2023) and TechRadar (Aug 2023). Both praise the fast 7940HS, the capable Radeon 780M iGPU, quiet and effective cooling, extensive connectivity (USB4, dual HDMI 2.1, up to four displays) and the compact metal chassis with a bundled VESA mount. Both note the plain design and constrained upgradability; Notebookcheck additionally flags weak 5 GHz Wi-Fi, the lack of an SD card reader, screws awkwardly hidden under the rubber feet, and that the 780M still stops short of a true gaming PC, while TechRadar calls the SSD speeds merely decent. (2 sourced reviews.)

**GMKtec NucBox K8** — Only one whitelisted tester, TechRadar, hands-on reviewed the exact base NucBox K8 (Ryzen 7 8845HS). TechRadar calls it the fastest AMD-powered NUC it had tested, praising CPU power, dual M.2 Gen4 slots and dual 2.5GbE LAN at a competitive price, while flagging the all-plastic silver build, awkward internal access and lack of Thunderbolt with only one of the CPU's two USB 4.0 ports exposed.
