Reviewer fan-noise observation Audible under full CPU load
VirtualizationHowTo found the system effectively inaudible at idle but said its fans ramped frequently and became noticeable during a full CPU load, more so than the reviewer's MS-01 systems.

Internal expansion 3x M.2 plus PCIe 4.0 x4
The MS-03 provides two PCIe 5.0 x4 M.2 positions, one PCIe 4.0 x1 M.2 position, U.2 support through the included adapter, and a physical PCIe x16 slot wired for PCIe 4.0 x4.

Reviewer expansion caveat Third M.2 limited to PCIe 4.0 x1
VirtualizationHowTo verified three internal M.2 slots but emphasized that the third is limited to PCIe 4.0 x1, so three identical NVMe drives should not be expected to deliver identical performance.

Reviewer value tradeoff $999 barebones; feature-dependent value
VirtualizationHowTo said the roughly $999 barebones price only makes sense for buyers who need the MS-03's combination of 10GbE, multiple NVMe slots, PCIe expansion, vPro, and newer processor; lighter virtualization needs have cheaper options.

Wireless worked in Robtech’s test
Robtech reported working Bluetooth and a full Valorant session over 5GHz Wi-Fi without network warnings. His router was about 12 metres away. He cautioned that one successful sample does not establish consistent wireless performance across units.

Wi-Fi struggled in Team Pandory’s test
Team Pandory could not complete an online speed test using the original Intel AX200 wireless card in his setup. Replacing it with a MediaTek RZ616 allowed the test to run. This differs from Robtech’s experience; their networks and units were not tested under identical conditions.

Batocera 41 connected to wireless devices
Team Pandory reported that Batocera 41 booted, connected to the local Wi-Fi network and paired with a Bluetooth controller. This checks basic connectivity on that review unit, not sustained wireless throughput or every Linux distribution.
