Buying Guide: What to Look For in Budget RGB Cases

When selecting an RGB case under £150, prioritise airflow first. Mesh front panels perform better than solid designs, and pre-installed fans save money. Check that the case supports your motherboard size (ATX, Micro-ATX, or Mini-ITX) and verify GPU clearance if using larger graphics cards.

RGB lighting quality varies considerably at this price point. Some cases offer integrated strips whilst others include individual RGB fans. Consider whether you want standalone control or iCUE/ARGB sync compatibility with your motherboard.

Cable management space matters even on budget models. Look for routing holes, velcro straps, and a PSU shroud to keep your build looking clean. Tempered glass panels are now standard at this price, so expect at least one side window.

Ensure the case includes sufficient mounting points for your cooling solution. Most budget options accommodate 240mm or 280mm liquid coolers in the front, with 120mm rear fan support. Verify dimensions before purchasing if space is limited in your setup area.
