What to Look for in an Airflow PC Case Under $150

At this price you can get genuinely great airflow without overspending. Here is what our team prioritized.

Mesh Front and Airflow Design

A mesh or perforated front (NZXT H5 Flow, Cooler Master Q300L) is the single most important airflow feature, letting cool air reach your components directly. Every pick here is built around strong airflow.

Included Fans

Fans add up, so cases that include several (MUSETEX with six ARGB fans, Antec Flux Pro) save money. Factor the cost of extra fans into cheaper cases that ship with only one or two.

Build Quality and Size

Even under $150 you can get solid build quality and good cable management (CORSAIR 4000D, Lian Li V100). Pick the size that fits your parts — micro-ATX (Q300L) for compact builds, ATX mid-tower for most.

Dust Filtering and Looks

Dust filters (Cooler Master Q300L) keep airflow strong over time, and options like the Fractal Design North’s wood front prove budget cases can look premium. For more, see the best airflow PC cases for gaming.
