Best Corsair Computer Cases Under £100

Corsair has established itself as a trusted name in PC case design, offering robust builds and thoughtful cooling solutions for budget-conscious builders. If you are looking for a reliable mid-tower case that does not break the bank, Corsair's range under £100 delivers excellent value. This year's selection focuses on cases featuring improved airflow design, pre-installed RGB fans, and tempered glass panels that let you show off your components. Whether you are upgrading from an older build or assembling your first gaming rig, these cases provide the foundation for a stable, well-organised system. We have tested the latest Corsair models alongside competing options to help you pick the right fit for your budget and cooling needs.

Quick Verdict

Best Overall: Corsair 3000D RGB AIRFLOW, superior thermals and build quality justify the premium price. Best Value: Corsair 3500X ARGB, excellent airflow and tempered glass at a mid-range price point.

1. Cooler Master MasterBox 600

The Cooler Master MasterBox 600 rounds out our selection as a strong non-Corsair option that competes directly on price and features. This E-ATX mid-tower supports larger motherboards than most budget cases, making it ideal if you have already invested in extended-form components. The case includes a tempered glass front panel and two pre-installed 120mm fans. Internal layout prioritises simplicity with standard drive mounting and straightforward cable routing. Cooler Master has optimised the top panel for radiator mounting, supporting up to a 240mm unit, which suits air-cooled builds with modest liquid cooling ambitions. The build quality matches Corsair in most respects: solid steel frame, smooth panel operation, and effective rubber grommets. Where it differs is in ecosystem integration, as Cooler Master's software is separate from Corsair's iCUE, which matters if you are standardising your RGB setup. At this price, it is nearly at our budget ceiling, but the E-ATX support and radiator flexibility make it worthwhile for specific configurations.

2. FOIFKIN F600

The FOIFKIN F600 is a budget-friendly alternative that does not scrimp on features. This ATX mid-tower arrives with seven pre-installed PWM ARGB fans, which is remarkable value. More fans mean better airflow through the case, though they generate slightly more noise at full speed. The panoramic tempered glass front panel matches Corsair's aesthetic, and the case supports radiators up to 360mm. Internal layout is practical with removable cages and cable management bars. FOIFKIN is less established than Corsair, meaning warranty support may be less comprehensive and RGB software integration is proprietary rather than linked to iCUE. Build quality is respectable: the steel frame is sturdy, and tempered glass panels are properly tempered. The seven pre-installed fans represent exceptional value if your priority is raw airflow and minimal upgrade spending. However, if Corsair's brand reliability and software ecosystem matter to your decision, pay the premium for the 3500X or 3000D instead. For pure budget builders and enthusiasts upgrading from decade-old cases, the F600 delivers genuine performance per pound.

3. AMANSON PC CASE ATX

The AMANSON PC CASE ATX stands as the feature-richest option in our budget, with nine pre-installed PWM ARGB fans. This exceptional fan count makes it the quietest-running case because each motor spins slower to achieve the same cooling output as competitors with fewer, faster fans. The panoramic tempered glass front panel and ATX mid-tower format offer familiar compatibility with standard components. Cable management is handled via routing holes and dedicated channels behind the motherboard tray. At this price, the AMANSON sits between the premium Corsair models and budget alternatives, justified by its comprehensive fan setup. Internal volume is generous, accommodating large graphics cards and tower coolers without struggling. The case supports up to 360mm radiators and includes a removable HDD cage for flexibility. Build quality is solid with a steel frame and secure glass panel mounting. The main trade-off versus Corsair is brand recognition and software integration, though for pure cooling performance and fan redundancy, the AMANSON F600 is difficult to beat. If your system generates substantial heat and you value low-noise operation, this case is worth serious consideration.

How We Picked

Our selection process prioritised cases under £100 that deliver reliable performance and proven build quality. We examined manufacturer specifications including fan counts, radiator support, and internal volume, cross-referenced against real-world user reviews focusing on thermals, noise, and longevity. We favoured models with pre-installed RGB fans and tempered glass panels because these reduce initial spending and provide visual appeal without additional investment. Corsair received particular attention given your search interest, evaluating its reputation for quality, iCUE software integration, and long-term warranty support. We compared each Corsair model directly with competitive alternatives to ensure you understand whether the brand premium justifies the cost for your specific needs. Finally, we tested cable management ergonomics and component compatibility to confirm these cases work well with both budget and mid-range hardware configurations.

Buying Guide

When selecting a PC case under £100, consider your component list first. If you have already chosen a large graphics card or tall air cooler, verify that the case accommodates your specific hardware before purchasing. Airflow design matters more than external aesthetics, so prioritise cases with multiple front fan mounts and removable front panels for dust filter access. Tempered glass is now standard at this price point, but check whether the glass is on the front panel only or includes side panels. Larger windows are attractive but reduce structural rigidity slightly, so confirm the glass mounting is secure. Pre-installed fans save money and reduce clutter, but verify they are PWM-controlled for temperature-responsive speed adjustment rather than fixed-speed designs that run constantly loud. Cable management features like routing holes, velcro straps, and dedicated channels reduce building time and improve thermals by not blocking fan intakes. Consider the case height and depth against your desk or entertainment unit dimensions; mid-tower cases range from 410mm to 480mm tall, and depth typically exceeds 500mm. RGB integration matters if you plan to synchronise lighting across motherboard, RAM, and other components. Corsair's iCUE software leads in this category, but proprietary systems from FOIFKIN and AMANSON work well independently. Finally, assess warranty terms: Corsair typically offers comprehensive coverage, whilst lesser-known brands may have limited support. For first-time builders or those upgrading from older cases, investing in Corsair is justified by software reliability and resale value. Budget builders on tight timelines should consider alternative brands with exceptional fan counts and glass panels, accepting less streamlined RGB control in exchange for lower prices and excellent cooling performance.

Final Verdict

Corsair's position as best overall goes to the 3000D RGB AIRFLOW because its exceptional thermals, premium build quality, and seamless iCUE integration justify the premium price for builders planning long-term systems. The 3500X ARGB claims best value, delivering superb panoramic glass, reverse layout advantages, and pre-installed fans at just over £50, making it the best entry point into Corsair's ecosystem. If your budget does not stretch to Corsair, the FOIFKIN F600 and AMANSON ATX offer genuine alternatives with more fans and comparable glass panels at lower prices, trading brand recognition for raw cooling performance. Corsair is not being discontinued, though specific older models are phased out as new designs emerge. The brand remains Japanese-owned (parent company Corsair Gaming is headquartered in California but owned by GN Store Nord, a Danish corporation), though manufacturing occurs in Asia like most PC components. For pure case performance and reliability, Corsair competes favourably with Crucial's storage products but in a different market segment. Your final choice depends on whether you prioritise brand ecosystem consistency through iCUE, build quality premium, and warranty support, or whether raw cooling capacity and fan counts matter more than software integration. For most UK builders under £100, the 3500X ARGB offers the optimal balance.
