Overview

The Okinos MiniArt 4 is a mini-tower PC case designed for MicroATX motherboards. Its black chassis combines mesh panels on the front and side to prioritize airflow, and it ships with three 120mm fans pre-installed so you can build a well-ventilated system right out of the box.
The power supply mounts at the front of the case, which frees up space for cable routing inside the main compartment. The top panel supports radiators up to 240mm, and both the top and bottom feature removable dust filters for easy maintenance. Expansion cards up to 330mm and CPU coolers up to 165mm tall are supported, giving this compact chassis more flexibility than its size suggests.
The front I/O includes a power button, one USB 3.1 port, one USB Type-C 3.2 Gen 2 port, and audio jacks. That makes it easy to connect modern peripherals and external storage at high speed. Overall, this is a practical mini-tower aimed at users who want to build a tidy entry-level or mid-range system without sacrificing cooling.

Compatibility Guide

The MiniArt 4 supports the MicroATX form factor. Standard MicroATX motherboards fit without issue, but ATX boards are not compatible, so check your motherboard's size before buying.
The power supply is installed at the front of the case, and standard ATX power supplies are supported. The layout is designed for easier cable management, but the length of your PSU can affect how much room you have for routing cables, so it is worth checking dimensions before assembly.
Graphics cards up to 330mm are supported, which covers most mid-range and many high-end models currently on the market. CPU coolers up to 165mm tall fit as well, so large air coolers and compact liquid coolers are both viable options. The top panel accepts a 240mm radiator, giving water-cooling builds room to breathe.
For storage, the case includes a shadow bay that accepts both 3.5-inch and 2.5-inch drives, plus a dedicated 2.5-inch shadow bay. That makes it convenient for users who want to combine an HDD with an SSD.

Product Info

The MiniArt 4 launched in January 2026, making it a relatively recent addition to the market. It sits in the entry-to-mid tier of PC cases, offering strong value for budget-conscious builders.
Including three 120mm fans as standard is a generous feature at this price point. The bottom intake fan is positioned to cool expansion cards directly, helping the compact chassis expel heat efficiently even under load.
The front USB Type-C port is another modern touch, allowing fast connections to the latest external drives and smartphones. With mesh panels for airflow and removable dust filters for maintenance, this case strikes a practical balance between cooling and convenience.

Best Use Cases

  • First-time PC builders: the MiniArt 4 works with a MicroATX motherboard and includes three 120mm fans, so you can set up a complete cooling solution without buying extra parts. It is not ideal for those who prefer the roominess of a full tower.
  • Users who want a tidy desk setup: the mini-tower footprint saves space while the mesh panels keep airflow strong. If you plan to install many expansion cards, a larger case would serve you better.
  • Enthusiasts trying liquid cooling: the top panel supports a 240mm radiator, making it easy to fit an AIO cooler. However, if you want a 360mm radiator, you will need a bigger chassis.

Things to Consider

The MiniArt 4 is a MicroATX-only case, so ATX and E-ATX motherboards will not fit. Double-check your motherboard's form factor before purchasing.
The front-mounted PSU layout improves cable routing flexibility, but depending on your power supply's cable length, you may need to plan the routing carefully. Also, while expansion cards up to 330mm are supported, the PSU position can sometimes interfere, so verify clearances during assembly.
When installing a 240mm radiator on top, check for potential conflicts with memory modules or motherboard VRM heatsinks. Because the chassis is compact, certain part combinations may require extra attention during installation.

FAQ

Q: Can I install an ATX motherboard in the MiniArt 4?
A: No, the MiniArt 4 is designed for MicroATX motherboards. ATX boards are too large and will not fit. Confirm your motherboard's form factor before buying.
Q: Are the included fans enough for adequate cooling?
A: Yes, three 120mm fans (two at the bottom and one at the rear) come pre-installed, which provides solid airflow for typical builds. If you want more cooling, you can add extra 120mm fans or a 240mm radiator on top.
Q: How long of a graphics card can I install?
A: The case supports expansion cards up to 330mm. Most mid-range and many high-end graphics cards will fit, but the PSU position can sometimes interfere, so it is wise to check dimensions before assembly.
