The GMKtec NucBox M3 Pro is a palm-sized desktop for home offices, small businesses and anyone who wants a full Windows PC without a tower under the desk. It runs a 13th Gen Intel Core i5-13500H with 12 cores and 16 threads (up to 4.7GHz) and Intel Iris Xe graphics, paired here with 16GB of dual-channel DDR4-3200 and a 1TB PCIe NVMe SSD, with Windows 11 Pro installed. A second M.2 slot and two SO-DIMM slots (up to 64GB) leave room to grow. Two HDMI 2.0 ports plus a front USB-C port drive up to three 4K screens, handy for spreadsheets, trading screens or a reception desk. Connectivity includes Wi-Fi 6, Bluetooth 5.2, 2.5G Ethernet and four USB-A ports (two of them 10Gbps). GMKtec quotes selectable 28W silent, 35W balanced and 40W performance modes with copper-pipe cooling, and the unit measures about 128.5 x 127 x 51mm, small enough to VESA-mount behind a monitor. Power comes from a 20V/5A external adapter.
