Our take on the KAMRUI AM21 Mini PC

The KAMRUI AM21 is a compact desktop built around AMD's Ryzen 7 8745HS, an 8-core/16-thread chip with Radeon 780M graphics. It handles everyday work, light gaming at 1080p, and media playback well, and its two SO-DIMM and two M.2 slots let you add memory and storage later. Compared with other mini PCs, it offers strong CPU performance and good expandability, but its integrated graphics won't match a dedicated GPU for demanding games. Reviewers praise its speed for the size, though some note the fan can get loud under load.
