Specifications side by side

Trade-Offs to Expect Under $30

For builds Under $30, you choose between compact enclosures, an open-frame test bench, and a wall mount. Enclosed models limit motherboard support to Micro-ATX or Mini-ITX form factors. Maximum graphics card clearances remain compact, topping out between 250mm and 256mm across the options. Cooling accommodation stays modest as well. Enclosed options provide CPU cooler clearance up to 135mm or rely on single 80mm fan layouts. Additionally, listed connectivity tops out at standard USB 3.0 ports, with no integrated lighting specifications present.

• Graphics card clearance is limited to 250mm or 256mm.
• Motherboard support excludes standard ATX in enclosed models.
• Case fan support relies on smaller 80mm sizes.
• CPU cooler clearance tops out at 135mm.

How We Selected These Products

You see 5 picks in this guide based entirely on published specifications and feature lists. Products are not physically handled or tested. You get direct comparisons of dimensions, motherboard compatibility, and component clearances extracted straight from manufacturer data. To keep choices distinct, each product family includes only one size or variant.

The guide arranges items with products in stock first. Listing data refreshes at least daily to keep your view up to date. Products appear here when qualifying for Under $30. Models move in or out as catalog listings adjust over time.

How to Choose the Right PC Case

1. Evaluate Radiator and Liquid Cooling

   Check if your planned cooling setup requires liquid cooling radiator brackets before selecting an enclosure. Most compact enclosures only accommodate low-profile air cooling blocks, whereas dedicated open frames offer mounting rails for liquid setups. For instance, the ALAMENGDA Open Frame Steel PC Test Bench provides mounting support for radiators up to 360mm. If you plan to install an all-in-one liquid cooler or custom loop, look specifically for published radiator size specifications rather than assuming a mini chassis has radiator mounting holes.

2. Measure CPU Cooler Height Clearances

   Examine the maximum CPU cooler height specification against your heatsink measurements. Compact mini towers feature narrow widths that prevent standard 160mm tower coolers from fitting inside. For example, the JOYJOM Compact Micro-ATX Case restricts CPU cooler height to 135mm. If you use a taller aftermarket tower cooler, the side panel will not close properly. You should always select low-profile horizontal heatsinks or compact air towers that stay well underneath the stated clearance limit to guarantee proper side panel closure and unobstructed internal airflow.

3. Inspect Included Case Fan Sizes

   Check whether the chassis includes active cooling fans or relies solely on passive ventilation. Smaller chassis designs often use compact fan mounts rather than standard 120mm mounts. For example, the UTLGAMENG Micro ATX Case includes an 80mm PWM fan for active exhaust. If your internal components generate substantial heat, you will need active airflow to prevent warm air from pooling. Review the fan diameter specifications and motherboard fan headers to confirm your board can control the fan speeds effectively.

4. Assess Sheet Metal Thickness Specs

   Review the material specifications and sheet metal thickness to ensure your hardware receives adequate physical protection. Thinner metal panels can bend during transit or flex under component weight. A model like the Iesooy Micro-ATX Steel Mini Case uses 0.8 mm steel construction, providing a rigid structure for your internal components. If you plan to transport your system often or want a rigid chassis that resists vibrations, check the manufacturer sheet thickness ratings and total chassis weight before making your choice.

5. Verify Mounting Dimensions and Load

   If you select a mounting bracket to suspend your case, compare your system dimensions against the bracket width adjustment range. The VIVO Adjustable Steel PC Wall Mount fits cases between 12.2 and 21.1 cm wide and supports up to 10 kg. Measure your fully assembled tower width, including any protruding side panel thumb screws, before mounting. Exceeding the width limit prevents safety straps from securing the chassis, while exceeding load capacity risks structural failure against the wall studs.
