What owners should know
- Two M.2 NVMe slots, which makes it a good pick for ZFS mirrors or a boot + data split.
- Usually costs more than the M920q on the used market because it is rarer.
Plex and Jellyfin transcoding
Handles 10-bit HEVC (typical 4K HDR) in hardware. No AV1 decode, so AV1 files fall back to the CPU. The table covers every CPU option sold in this chassis. Check which CPU a listing actually has.
| Video engine | H.264 | HEVC 10-bit decode | VP9 | AV1 decode | HEVC encode |
|---|---|---|---|---|---|
| Intel Quick Sync (Kaby Lake–Comet Lake) | Yes | Yes | Yes | No | Yes |
Plex needs a Plex Pass for hardware transcoding; Jellyfin does not. More detail in our Quick Sync generations guide.
Before you buy one used
- Confirm the exact CPU model in the listing photos or System Information screenshot, not just "Core i5".
- Check that a power adapter of the right wattage is included (135 W). Many ex-office units ship without one.
- Ask whether the BIOS is unlocked. Ex-corporate machines sometimes keep an admin password.
- A 2.5" drive needs the caddy and cable, which are often missing when a unit shipped with only an M.2 SSD.
- The PCIe riser is usually not included. Budget for it separately.
