SilverStone Milo 11 Slim Micro-ATX Chassis - Compact Media/Office Case

Our review of the SilverStone Milo 11 finds it best for users who need a legitimately compact Micro-ATX enclosure for a home theater PC or small office build where space and quiet operation matter most. The single biggest reason to buy is its combination of a sturdy steel frame at only 10.35L and support for a TFX power supply and a slim optical drive, which makes it a rare small-volume case that still accepts discrete graphics up to 272mm. This review covers the layout, features, and real-world fit for common HTPC and compact workstation setups.

Key Features

• 10.35L slim footprint: The small chassis volume keeps a desktop or AV cabinet tidy while still hosting Micro-ATX or Mini-ITX motherboards for flexible builds.
• TFX PSU support: Designed for a TFX form factor power supply so builders can use low-profile power units without compromising internal clearance.
• Horizontal or vertical orientation: Mounting options let the Milo 11 adapt to shelf or tower layouts, which is useful in living rooms or limited-desk spaces.
• Slim optical drive compatibility: An external opening for a 9.5mm slim ODD supports media playback and legacy discs without external adapters.
• Top drive bracket: The included bracket accepts 1 x 2.5 SSD plus a 2.5/3.5 combo bay, simplifying storage choices in a compact enclosure.
• GPU clearance: Support for graphics cards up to 272mm allows a modest discrete GPU for light gaming or GPU-accelerated tasks in a small chassis.

Who It's For

The Milo 11 is aimed at HTPC builders, small office users, and anyone who needs a compact PC that still accepts Micro-ATX motherboards and a discrete GPU up to 272mm. Its slim 10.35L footprint and support for a slim optical drive make it particularly attractive for media-centre installations where an ODD and compact profile are required.

Those who need ATX power supplies, extensive airflow for high-end CPUs, or multi-GPU high-performance gaming rigs should look elsewhere, since the chassis is built around the TFX PSU format and modest internal volume rather than expansive cooling or large PSUs.

Pros & Cons

Pros

• Very compact 10.35L steel chassis that still accepts Micro-ATX and Mini-ITX boards for flexible builds.
• Supports TFX form factor PSUs, keeping the internal layout compact and suitable for low-profile builds.
• Includes a top drive bracket for 2.5 SSD and a 2.5/3.5 combo bay plus an external slim ODD slot for media use.
• Can fit a discrete graphics card up to 272mm, enabling light GPU upgrades in a small case.

Cons

• Requires a TFX PSU sold separately, which may limit power options compared with standard ATX builds.
• Small volume constrains cooling and large component choices compared with larger towers.
