Mechanic Master C34Plus Portable Desktop ATX Case - Ultra-Compact

In this review the Mechanic Master C34Plus is presented as a compact, capable chassis for builders who need full ATX compatibility without sacrificing desktop space. The bottom line: it is for users who want a minimalist enclosure that still accepts full-size components and efficient cooling. The single biggest reason to buy is its rare combination of an ultra-compact open-frame aluminum body that supports full ATX and extra-long GPUs, delivering a small footprint build without forcing compromises on parts selection.

Key Features

• Ultra-Compact Design: The case supports full ATX and 27cm-wide EATX motherboards in a much smaller footprint, letting a full-featured system sit comfortably on a desk or shelf.
• 240mm AIO Compatibility: It accepts 240mm AIO liquid coolers while accommodating RAM up to 44mm in height, enabling effective CPU cooling in a compact layout.
• Extra-Long GPU Support: Fits graphics cards up to 38cm in length, so gamers can use high-performance GPUs without trimming options.
• Flexible PSU Options: Compatible with ATX 14cm and SFX power supplies, offering flexibility for builders who prioritize cable routing or small PSUs.
• Efficient Thermal Layout: The open-frame design with mesh panels promotes airflow across components for balanced cooling and quieter fans.
• Aluminum Alloy Construction: A lightweight but sturdy aluminum frame protects components while keeping the case easy to move with its built-in handle.

Who It's For

The C34Plus is best for enthusiasts and gamers who need a small desktop footprint but want to keep full-size components like standard ATX motherboards and long GPUs. It suits compact desk setups, LAN-event users who value a carry handle, and builders who plan to use a 240mm AIO for strong CPU cooling.

Those who need extensive drive bays, tower air coolers taller than typical AIO setups, or absolute silence in a fully enclosed case should look elsewhere. Users requiring many 3.5in drives or very tall memory modules may find the internal space too streamlined for those specialized builds.

Pros & Cons

Pros

• Supports full ATX and 27cm-wide EATX motherboards in a notably compact chassis.
• Accepts 240mm AIOs with RAM clearance up to 44mm for effective cooling without tall-memory compromises.
• Houses extra-long GPUs up to 38cm, preserving high-end graphics options for compact builds.
• Aluminum alloy construction keeps weight down while providing a premium, durable finish and a convenient handle.

Cons

• Streamlined internal space means custom cable routing can be tight and may require careful planning.
• Open-frame layout with mesh panels provides less acoustic dampening than a fully enclosed case.

Specifications
