This article covers オキノス Aqua 3 Micro ATXケース MATX PCケース 120mm ARGBファン3個付き パノラマビュー強化ガラスフロント&サイドパネル Type Cポート付き ブラック.

Overview

Okinos introduces the Aqua 3, a Micro-ATX case that punches well above its price tag by offering a 270-degree panoramic tempered glass design. The front and side panels are fused into a single curved glass panel, giving you an unobstructed view of your build. Out of the box, three 120mm ARGB fans come pre-installed—two at the top and one at the rear—so you can start building immediately without additional cooling purchases. Priced around ¥16,000, this case targets budget-conscious builders who still want a showpiece.
The case measures 350mm deep, 210mm wide, and 392mm tall, supporting both Mini-ITX and Micro-ATX motherboards. It can accommodate graphics cards up to 320mm and CPU coolers up to 164mm tall, making it compatible with most mid-range to high-end GPUs and tower coolers. The front I/O panel includes two USB 3.0 ports, a USB 3.2 Gen 2 Type-C port (10Gbps), and separate audio jacks, offering modern connectivity at an affordable price point.
A built-in 4-port ARGB fan controller allows synchronization with your motherboard or standalone control via the case button. The 1.2mm fine mesh steel panels and magnetic dust filters (top and bottom) strike a good balance between airflow and dust prevention. All in all, the Aqua 3 is a compelling option for builders who want a clear view of their hardware without breaking the bank.

Compatibility Guide

  • Motherboard support: Micro-ATX and Mini-ITX only. Standard ATX boards will not fit.
  • Power supply: Bottom-mount design accepts standard ATX PSUs. Modular units are recommended for easier cable management.
  • Graphics cards: Up to 320mm length. Most current GeForce RTX 4070-class cards and similar will fit, but triple-slot ultra-long cards may need clearance verification.
  • CPU coolers: Maximum height 164mm. Most tower-style air coolers fit; for liquid cooling, a 240mm radiator can be mounted on the top, though motherboard clearance may be tight.
  • Storage: Two 2.5-inch SSDs and one 3.5-inch HDD can be installed.

Product Info

The Okinos Aqua 3 (model OKICC-AQUA3-MATXB-H3BA) launched in early 2024 as an entry-level to mid-range Micro-ATX case. Its retail price hovers around ¥16,000, which is remarkably low for a panoramic glass chassis with three ARGB fans and a built-in fan controller. The market positioning is clear: this is a value-oriented case that doesn't sacrifice aesthetics. The 270° glass view was previously exclusive to premium cases; bringing it to this price point is the key differentiator.
Cooling is based on a vertical airflow path: two top exhaust fans and one rear exhaust fan. The case does not include front intake fans, but the side mesh panel allows air to be drawn in naturally. Performance is adequate for typical mid-range builds, though users with high-power components may want to add an intake fan.

Best Use Cases

  • First-time PC builders: With three included fans and a pre-installed ARGB controller, wiring complexity is reduced. The spacious interior makes part installation straightforward, ideal for beginners.
  • Theme-oriented gaming PCs: The panoramic glass is perfect for showcasing RGB fans, custom cables, or water-cooling loops. It pairs beautifully with white or themed components.
  • Budget-conscious gamers: Looking to build a Micro-ATX gaming PC on a tight budget? The Aqua 3 gives you premium looks without the premium cost. It's best paired with air-cooled builds.
  • Who should NOT buy: If you need an ATX motherboard, plan to install a 360mm radiator, or require silent PWM-controlled fans out of the box, look elsewhere.

Things to Consider

The most significant limitation is radiator compatibility. While a 240mm radiator can be mounted at the top, clearance between the radiator/fans and the motherboard VRM heatsink is tight. Some thick radiators may not fit with certain boards. The case does not officially support 240mm AIO, so always check measurements before purchasing.
All three included fans are 3-pin DC fans, not 4-pin PWM. This means you cannot control their speed precisely via the motherboard; they run at a fixed voltage unless you manually adjust it. If near-silent operation is important, consider replacing them with PWM fans.
Additionally, the build quality is decent for the price, but the glass panel can feel somewhat thin, and the rubber grommets for cable management are basic. The quick-release glass panel is a nice touch, but the retention mechanism relies on rivets—be careful when removing.

FAQ

Q: Can I install an ATX motherboard in this case?
A: No. Only Micro-ATX and Mini-ITX motherboards are supported.
Q: Will a 240mm AIO cooler fit?
A: It may fit on the top, but clearance issues with the motherboard are possible, especially with boards that have tall VRM heatsinks. Check your specific motherboard and radiator thickness before purchasing.
Q: Are the included fans PWM?
A: No, they a
