GMKtec
The NucBox M5 Plus is GMKtec's Ryzen 7 5825U mini PC in a 128.8 x 127 x 47.8 mm case. The 5825U is an 8-core, 16-thread Zen 3 laptop chip with Radeon Vega integrated graphics, and it runs from a modest 65 W adapter. It takes two DDR4-3200 SO-DIMMs up to 64 GB and a PCIe 3.0 NVMe SSD. It has two Realtek 2.5 GbE ports, which makes it a good, frugal choice for a pfSense/OPNsense router, a Proxmox node, or a home server that needs to sit on two networks. It also has four USB-A ports, HDMI, DisplayPort and a 10 Gbps USB-C port, but no USB4. The Vega graphics are fine for desktop use and video but weak for gaming next to 680M or 780M systems.

Buying guide
Only 2 M5 Plus listings turned up, so there's no market read here. Both are the Ryzen 7 5825U with 32 GB: an auction currently at about $250 with a 1 TB SSD, and a $450 fixed-price unit with 512 GB from a seller named gmktec-official. Confirm it's the M5 Plus (5825U) rather than the M5S or M5 Ultra, and that the 19 V / 3.42 A barrel adapter is included.
$250.00delivered
The lowest price right now: an auction at about $250 delivered with 1 bid and nearly 4 days left, for a 5825U with 32 GB, a 1 TB SSD and Wi-Fi from a 100% seller. It will climb, so set a limit under the $450 fixed-price unit; 32 GB and dual 2.5 GbE are plenty for Home Assistant.
