The MSI MAG FORGE 120A PC Case is an outstanding budget airflow case that punches well above its weight class. At £54.95, it offers remarkable value for first-time builders and anyone seeking excellent thermal performance without premium pricing.
What I Tested: Real-World Methodology
I tested the MSI MAG FORGE 120A PC Case over a three-week period with two different system configurations. The first build featured a Ryzen 5 7600X with an RTX 4060 Ti, whilst the second used an Intel Core i5-13400F paired with an RTX 4070. Both systems included 32GB of DDR4 RAM and multiple storage drives to simulate realistic gaming setups.
My testing focused on thermal performance, build quality, ease of assembly, and noise levels. I measured CPU and GPU temperatures during extended gaming sessions using HWiNFO64, recorded noise levels with a decibel meter at various fan speeds, and documented the entire build process to identify any potential issues. I also stress-tested both systems with Cinebench R23 and FurMark to push the cooling system to its limits.
Throughout testing, I paid particular attention to cable management options, component clearance, and the quality of included accessories. I built each system twice to verify that my initial impressions weren’t flukes and to test different cable routing strategies.
Price Analysis: Exceptional Value Territory
Currently priced at £54.95, the MAG FORGE 120A sits comfortably in budget territory. However, the 90-day average of £48.24 suggests you might catch it on sale if you’re patient. Even at its current price, the value proposition remains compelling when you consider what’s included.
Six pre-installed RGB fans alone would cost £40-60 if purchased separately, making the case itself essentially free once you factor in the fans. Most budget cases include one or two fans at best, leaving you to spend extra on additional cooling. MSI’s approach here is genuinely refreshing and makes this case a standout choice for builders on tight budgets.
Compared to similarly priced alternatives like the Corsair 4000D Airflow (around £85) or the Fractal Design Focus G (approximately £50), the MAG FORGE 120A offers better out-of-the-box cooling performance. The Fractal case includes fewer fans, whilst the Corsair option costs significantly more despite its excellent build quality.
Cooling Performance: Where This Case Truly Shines
The mesh front panel isn’t just for show. During my testing, the MAG FORGE 120A delivered impressive thermal results that rival cases costing twice as much. With the Ryzen 5 7600X and stock cooler, I recorded idle temperatures of 32°C and gaming loads peaking at 68°C. The RTX 4060 Ti maintained 71°C during extended gaming sessions, which is excellent for a budget case.
The six 120mm fans create positive air pressure when configured correctly (three intake, three exhaust), which helps reduce dust accumulation. I measured airflow at the front panel and found minimal restriction compared to cases with solid fronts and side vents. The mesh design genuinely prioritises function over form, though MSI has managed to make it look decent too.
Noise levels remained reasonable even under load. At maximum fan speeds, I measured 42 decibels from one metre away, which is noticeable but not intrusive. Setting the fans to 60% speed reduced noise to 35 decibels whilst maintaining excellent cooling performance. The included fan controller makes adjusting speeds straightforward without requiring motherboard headers.
One minor disappointment: the top panel lacks complete mesh coverage. Whilst it includes a magnetic dust filter, the solid sections reduce exhaust efficiency slightly. However, this didn’t significantly impact overall thermal performance in my testing.
Build Quality and Design: Solid Foundation
The steel construction feels reassuringly solid, though the case does weigh less than premium alternatives. The 4mm tempered glass side panel fits securely and removes without tools, making component access straightforward. I appreciated the thumb screws rather than clips, as they provide better long-term reliability.
Internal layout follows standard ATX conventions with no surprises. The power supply mounts at the bottom with a dedicated shroud that hides cables effectively. Three 2.5-inch SSD mounting points sit behind the motherboard tray, whilst a removable dual-bay cage accommodates 3.5-inch hard drives or additional SSDs.
Cable management proved easier than expected for a budget case. Rubber grommets at key pass-through points protect cables, and the 20mm clearance behind the motherboard tray provides adequate space for routing. I managed to achieve a clean build without excessive struggling, though premium cases like the Corsair 5000D offer more sophisticated cable management solutions.
The RGB implementation deserves mention. The six fans connect to an included controller that offers multiple lighting effects. Whilst not as sophisticated as addressable RGB systems, the lighting looks vibrant through the tempered glass panel. You can also connect the controller to your motherboard’s RGB header for synchronised lighting with other components.
Component Compatibility: Room for Modern Hardware
The MAG FORGE 120A accommodates GPUs up to 330mm in length, which covers most modern graphics cards including the RTX 4070 Ti and RX 7800 XT. My RTX 4070 (300mm) fitted comfortably with room to spare. CPU cooler clearance reaches 160mm, sufficient for popular tower coolers like the Arctic Freezer 34 eSports DUO or be quiet! Pure Rock 2.
Radiator support extends to 240mm units at the front or top, making this case suitable for entry-level liquid cooling setups. I didn’t test with an AIO during my review period, but the mounting points appeared standard and well-positioned. Note that installing a front radiator will require removing the pre-installed intake fans.
Storage options include three dedicated 2.5-inch SSD mounts and a removable cage for two 3.5-inch drives. This configuration suits most modern builds, though heavy storage users might find it limiting. The cage removal provides extra clearance for longer power supplies or improved airflow if you’re running an all-SSD setup.
ATX, Micro-ATX, and Mini-ITX motherboards all fit without issues. The standoff positions are clearly marked, and MSI includes a decent selection of screws and standoffs in the accessory box. I particularly appreciated the included cable ties and Velcro straps for cable management.
