I built the biggest OCuLink mini PC : a palm-sized GMKtec EVO-T1 strapped to an RTX 4090 via OCuLink. In this build we unbox, tear down, liquid-metal the CPU, bolt on both FLEX-ATX and full ATX PSU options, and benchmark everything—from integrated Arc graphics to a 4090 over a Gen4x4 OCuLink link. Expect real numbers, real quirks, and a ridiculous amount of fun.

What you’ll see

GMKtec EVO-T1 (Intel Ultra 9 285H, up to 80W “Performance” mode in BIOS), dual-fan design, Thunderbolt + OCuLink, 64–128 GB DDR5, up to three NVMe slots
Arc 140T iGPU gaming (Cyberpunk, God of War, GTA V, Minecraft) + local LLM tests (DeepSeek via different launchers; GPU + NPU notes)
Liquid metal attempt (with safety taping) and the very modest temp gains vs stock compound
Two eGPU builds: compact (FLEX-ATX + RTX 4060) and “go big” (ATX PSU + 600W adapter + RTX 4090 with bracket)
