5 Things to Know About the Beelink SER5’s Size and Storage
- The case measures 126 × 113 × 42 mm, which is compact but not the smallest mini PC on the market.
- The 2.5-inch bay only fits drives up to 7 mm thick, so thicker hard drives or SSDs won’t work.
- The single M.2 slot is strictly for 2280-length NVMe drives — no SATA M.2 or shorter cards are supported.
- You cannot install both a 2.5-inch drive and an M.2 drive simultaneously; choose one.
- The small chassis limits airflow, so expect higher temperatures under sustained load.
