This article covers CoolerMaster MasterBox CM695 光学ドライブ対応5.25インチベイ搭載 ミドルタワーケース「MasterBox CM695」 スチールサイドパネル搭載モデル [CM695-KN5N-S00].

Overview

The Cooler Master MasterBox CM695 is a mid-tower PC case that stands out for retaining a 5.25-inch optical drive bay—a feature that's becoming rare in modern chassis. If you still rely on a DVD or Blu-ray drive, or want to install a front-panel device like a fan controller, this case offers a practical and nostalgic solution.
Measuring 477×209×488.5mm (with protrusions), the CM695 supports ATX, Micro-ATX, and ITX motherboards. It can house graphics cards up to 398mm long and CPU coolers up to 166mm tall. Three pre-installed ARGB fans and dust filters on the top, front, and bottom come standard, giving you a solid foundation for airflow and lighting.

Connectivity & Compatibility

The front I/O panel includes three USB 3.0 ports and audio jacks. Inside, the storage layout is generous: one 5.25-inch bay, four 3.5-inch bays, and five 2.5-inch bays—ideal for building a high-capacity storage rig.
Motherboard compatibility covers ITX, Micro-ATX, and ATX form factors. The power supply can be up to 180mm long, and there's ample room for cable management behind the motherboard tray. The steel solid side panel helps reduce noise compared to glass-panel cases.

Product Info

Released in late 2025, the MasterBox CM695 carries a retail price around ¥22,980. It sits in the mid-range segment, specifically targeting users who need an optical drive bay—a niche that Cooler Master serves well. The warranty is two years, and accessories include a basic hardware kit and manual.
Market positioning: one of the few current cases that still offers a 5.25-inch bay while maintaining modern cooling support and a clean appearance.

Best Use Cases

  • Users who need an optical drive – Whether you rip CDs, watch Blu-rays, or install legacy software, this case is one of the best choices available today. It's rare to find a new case that accommodates a 5.25-inch drive without sacrificing modern features.
  • High-storage builders – With four 3.5-inch and five 2.5-inch mounts, you can pack plenty of HDDs and SSDs for a home server or video editing workstation. The spacious interior allows for a large GPU as well.
  • Noise-conscious builders who like a touch of RGB – The steel side panel dampens sound, and the three ARGB fans provide subtle lighting without a glass window being necessary.
    If you need a front USB-C port, note that this model only provides USB 3.0 Type-A. Also, those wanting extreme water-cooling capacity may find the radiator support (360mm top, 280mm front) adequate but not exceptional.
