MSI PRO SHIELD M100P Micro-ATX Mini-Tower PC Case (306-7G31M21-HH9)

A Compact, Unlit Foundation for a Practical Desktop

MSI PRO SHIELD M100P is a compact mini-tower case for a separately configured Micro-ATX or Mini-ITX desktop. Its straightforward exterior and non-ARGB rear fan suit an understated system where convenient front connections and a measured component layout matter more than a glass showcase or decorative lighting.

The 312 x 166 x 354mm enclosure provides four expansion slots, four front USB-A ports and support for an ATX power supply up to 160mm long. Check the 275mm GPU and 140mm CPU-cooler limits before selecting parts; a small case does not automatically fit every Micro-ATX build, and a power supply or complete PC is not included by this listing.

Best For: Compact office desktops, Micro-ATX PC builds, Mini-ITX configurations, Unlit workspaces, Measured replacement enclosures, Front USB convenience

DETAIL SPECIFICATION

TECHNICAL FEATURES

Understated rather than a glass display build

The PRO SHIELD M100P uses a practical mini-tower layout with non-ARGB cooling. It suits a clean desktop configuration without implying that decorative lighting, a side window or additional fans are supplied.

Four front USB-A ports

Two of the front Type-A ports are specified at 5Gbps, while two additional Type-A ports provide further connections. Actual operation requires the corresponding motherboard headers; the case does not add missing motherboard connectivity.

Small footprint requires a complete fit check

Motherboard size alone does not establish compatibility. Measure the graphics card and its power cable, CPU cooler and ATX PSU with attached leads against the enclosure limits.

One included rear cooling fan

The standard configuration contains one 80mm non-ARGB rear fan, with support for an 80mm or 90mm rear position. Plan cooling for the actual components instead of assuming high-end gaming airflow or a radiator layout.
