Where the GMKtec NucBox M5 Ultra (32GB + 512GB) stands out is its home-lab focus: two 2.5G Ethernet ports, a quiet dual-fan build and a lower entry position on price, with the same 32GB of memory but an older Ryzen 7 7730U and a 512GB drive. The Geekom IT13 (2TB) also adds an SD reader, dual USB4 ports, a 2.5-inch bay and an M.2 2242 slot, so it stores far more out of the box. Choose the Geekom IT13 (2TB) for a small, fast, storage-rich workstation or media server, and the GMKtec NucBox M5 Ultra (32GB + 512GB) for a cheaper networking-first virtualization node.

The Geekom IT13 (2TB) ships a 2TB Gen 4 SSD and adds an M.2 2242 SATA slot and a 2.5-inch bay, while the GMKtec NucBox M5 Ultra (32GB + 512GB) ships 512GB across two PCIe 3.0 M.2 slots. The Geekom holds far more out of the box.

Which one to buy if

What owners say

Owners of the two machines buy them for different jobs, and both groups are happy with what they got. Geekom IT13 (2TB) owners call it a small, quiet powerhouse, using it for 4K video and photo editing, digital audio work, local AI models and an always-on Plex server, and they like the metal build, the dual HDMI outputs and the three-year warranty; their cautions are integrated graphics for gaming, warmth under long loads and inconsistent support. GMKtec NucBox M5 Ultra (32GB + 512GB) owners value the performance per watt and the dual 2.5G networking for pfSense, Proxmox and Linux desktops, and several single out fast, helpful support; the platform is older DDR4 and PCIe 3.0, and one owner hit a sleep-wake fault.
