The Best Mini-ITX Cases for 2018: 10 Small Form-Factor Computer Cases Reviewed

NZXT Manta

The NZXT Manta case resembles an ATX tower case reduced to fit Mini-ITX motherboards. For example, the PSU compartment was placed at the bottom of the case.

But its reduced size still provides enough space for appropriate cooling using air and liquid cooling units. The case supports up to three radiators and two liquid reservoirs. It comes with two 120 mm intake fans, installed at the front of the case.

The elegant design of the reinforced steel panels makes this one of the most visually appealing cases in its price range—and the curved panels improve the functionality of the case. At 18.5 x 11.6 x 19.4 inches, the Manta offers twice the cable management space compared to some other cases, with numerous cable tie points and massive clearance.

A long space in front of the Mini-ITX motherboard permits graphics cards up to 420 mm long.

With two USB 3.0 ports, two 3.5 mm audio jacks, and the PSU compartment placed at the bottom of the case, the Manta allows for smart LED control. One small button can switch the lights between four settings. NZXT provided no lighting for the system area.

The large window panel on the side of the case is one of its chief selling points, though you can buy a windowless option. NZXT sells the Manta in black and white, black and red, and all black.

Weighing approximately 16 pounds, this compact system makes a sleek, impressive case for any gaming rig.

SilverStone FT03B-MINI

Half the size of the original FT03B micro-ATX case, the SilverStone FT03B-MINI case is a unique mini-ITX form factor shell with a compact and minimalist design. SilverStone reconfigured its Fortress FT03 for mini-ITX motherboards, improving on the original case and remaining true to its most well-received features.

Weighing less than 13 pounds, the FT03B-MINI measures 13 x 11 x 19 inches, making it one of the smaller cases available in its price range. The black outer shells are 2.5mm-thick sandblasted, anodized aluminum panels. The enclosure itself is made of steel.

The FT03B-MINI’s thermodynamic layout encourages stack effect cooling, with the Mini-ITX motherboard mounted at a 90° rotation as is common in SilverStone cases. Hot air naturally rises to the top and exits the vents on four sides of the case. SilverStone includes a 140mm Air Penetrator intake fan and supports entry-level liquid cooling.

With two USB 3.0 ports and audio jacks for both headphone and mic, the FT03B can accommodate graphic cards up to 10 inches long and supports one 3.5-inch drive and two 2.5-inch drives. It uses an SFX power supply and does not contain cable connectors—the removable back cover was designed for external cable management.

The FT03B-MINI’s efficient, organized layout requires careful adherence to the factory instruction manual for maximum optimization. The super-mini footprint is ideal for gamers looking to save space or grab their system and go. A removable bottom filter prevents dust buildup and makes for easy maintenance.

The FT03-MINI also comes in silver.

Thermaltake Core P1

The Thermaltake Core P1 is a mini-ITX case that menses in at 16.6 x13.1×15 inches and weighs just over 20 pounds. Its tempered glass design makes it a visually attractive option, allowing everyone to see the inner workings of your genius set up.

It has two 2.5-inch external drive bays. Internally you have one 3.5 inches and one 2.5-inch option. The Core P1 has five expansion slots and can accommodate a 6.7×7.6-inch motherboard (aka a mini-ITX).

The front I/O panel features two USB 3.0 ports and one HD audio connection. It optionally runs a Standard PS2 PSU.

There are two 120mm internal fans on the left side of the case which provide the system with adequate cooling ability. There are some models in this category that can accommodate more fans, so if overheating is a concern, be sure to research those.

In terms of the case clearance, you have a CPU cooler height limit of 6.69 inches, and a VGA length limit of 14.96 inches. The radiator measures in at a thickness of 1.78 inches without the fan. Your radiator width is limited to 4.72 inches, and your PSU can’t be longer than 7 inches.

This budget friendly option comes in at under $100, but it looks like some of the more expensive model’s available thanks to the tempered glass aesthetic.

Corsair Obsidian 250D

The Corsair Obsidian 250D is a cubic case with a design consisting of hard, clean lines. Weighing less than 10 pounds, the aluminum, steel, and plastic case measures 13.8 x 10.9 x 11.4 inches. Tall feet at the bottom elevate the case off of any supporting surface.

With two USB 3.0 ports and audio jacks for both headphone and mic, the Obsidian 250D offers comparable functionality to other Mini-ITX cases. But due to its size and its blocky shape, this shell would support a stationary gaming rig better than one intended for portability.

This model from Corsair can fit two 3.5-inch drives and two 2.5-inch drives. Depending on your configuration, the shell is also capable of fitting a 5.25-inch drive, a full-sized PSU, a 290mm graphics card, and a 240mm radiator fan.

Liquid coolers with 120mm radiators can also be installed here. Two 80mm fans can also fit at the rear of the case.

Vents in each side and back panels assist the flow of air. Dust filters can be easily removed from beneath all intakes.

Silverstone SG05-LITE

An incredible bargain, the SilverStone Tek SG05-LITE is less than half the price of the black SG05-USB3.0 and offers much of the same functionality. Smaller and lighter than the SG05, the SG05-LITE weighs less than 7 pounds and measures 11 x 10 x 14 inches.

While this case offers less in aesthetic design than others, its compact layout allows for a high-powered gaming build.

Engineered for use with Mini-DTX and Mini-ITX motherboards, this SilverStone offering balances cooling and quiet. The case includes a massive 120mm intake fan mounted in the front for positive pressure cooling and supports retail-boxed CPU coolers. A fan of this size is unprecedented for small form factor builds, and it pulls its weight, reaching 1200 rpm.

The wide and numerous vents in the side and on the top of the case’s white, plastic shell allow for ample airflow to assist in the ventilation of the components.

The Tek SG05-LITE offers two USB 3.0 ports and audio jacks for both headphone and mic. It accommodates graphics cards up to 10 inches long and supports one 2.5-inch drive and one 3.5-inch drive.

The main difference between the SG05-LITE and the higher-priced SG05 is the 80 Plus certified SFX 300W power supply included in the costlier model. Though not included here, the remaining functionality and the impressively light, mini-cube size makes the SG05-LITE a true bargain. The LITE model allows for greater flexibility in choosing components at a more affordable price.

The Tek SG05 case comes in black and white.

If you’re looking for a mini-ITX for well under $50, the Cooler Master Elite 110 is a strong contender. Its mesh front panel design provides excellent airflow from front to back, and the internal 120mm water cooling system front fan and 80x15mm side fan work to keep the system cool and running at max capacity.

The max VGA card length is 8.3 inches, and the max CPU cooler height is 3 inches. If you want to utilize the full cable management capabilities, your PSU is limited to 5.6 inches long. With less cable management, you can stretch that to 7.1 inches long.

The system supports standard sized ATX power supplies up to 180mm long. The front I/O panel includes connectivity for two USB 3.0 ports and one audio in and out port.
