4/5

$2,879 – $3,039

The enthusiast's Strix Halo box. Same 128GB unified memory as the others, but the MS-S1 Max brings the strongest IO and cooling of the group: dual 10GbE, dual USB4 v2 (80Gbps), a PCIe x16 slot, a 320W internal PSU, and a 2U-rack-mount option for multi-box LLM clusters. ServeTheHome called it 'the best Ryzen AI Max mini-PC yet.'
