Beelink GTi12 Ultra (Core i9-12900H)
The GTi12 Ultra is Beelink's larger Intel mini PC with a Core i9-12900H (6 P-cores and 8 E-cores, 20 threads) and Iris Xe graphics. Its standout features are a built-in 140 W power supply, two 2.5 GbE ports, Thunderbolt 4, a fingerprint reader in the power button, and a bottom PCIe x8 connector for Beelink's EX GPU dock, which takes a full-size desktop graphics card. It has two DDR5 SO-DIMMs and two PCIe 4.0 x4 NVMe slots. ServeTheHome measured 6 to 9.5 W idle, just over 105 W max, and under 38 dBA unless pushed hard for a long time. The big downside is servicing: ServeTheHome removed more than 20 pieces to reach the memory and SSDs. It suits a homelab node or a desktop that can later add a real GPU.

Check before you buy
- Ask the seller to confirm the installed RAM and SSD sizes; upgrading means removing 20+ parts.
- The EX GPU dock is a separate product; check whether it's included if you want eGPU expansion.
- There's no external brick (the PSU is built in), so you only need a standard AC cord.
- Wi-Fi is the older Intel AX200 (Wi-Fi 6); swap to an AX210 if you need 6 GHz.
General off-lease checks (BIOS passwords, Computrace, missing drive caddies) are in the used mini PC buying checklist.
