It combines a full mesh front panel with a right-side intake design to maintain stable cooling performance even under heavy loads. Four 120mm ARGB fans come pre-installed, and the case supports radiators up to 360mm on both the front and top, making it suitable for high-end builds. This case supports E-ATX, ATX, Micro-ATX, and Mini-ITX motherboards, with clearance for graphics cards up to 400mm, CPU coolers up to 165mm, and ATX power supplies up to 235mm. The front I/O panel includes one USB Type-C port, two USB 3.0 ports, and HD Audio, covering everyday use and gaming scenarios alike. Positioned in the entry-to-mid tier, the PONOS ULTRA MS4 offers four ARGB fans and 360mm radiator support as standard while keeping the price accessible. It is a strong choice for users who prioritize value without sacrificing cooling capability or modern connectivity. ## Compatibility Guide The PONOS ULTRA MS4 supports E-ATX, ATX, Micro-ATX, and Mini-ITX motherboard form factors. When installing an E-ATX board, the internal layout still leaves enough room for large graphics cards and CPU coolers, though cable management space may be slightly tighter. Graphics cards up to 400mm in length are supported, which covers virtually all current high-end GPUs. CPU cooler clearance is 165mm, so be sure to check the height of any large air cooler or AIO pump block before purchasing. The power supply mounts at the bottom and supports ATX units up to 235mm in length. For liquid cooling, radiators up to 360mm can be installed on both the front and top. This flexibility allows for a variety of cooling configurations, whether you prefer a simple air-cooled setup or a full custom loop. Storage drive support should be verified against the official specifications before planning your build. ## Product Info The PONOS ULTRA MS4 is a mid-tower PC case released as part of RAIJINTEK's second-generation PONOS series. It weighs approximately 6.9kg and is available in black only. The chassis is made of metal and features a hinged tempered glass side panel for easy access to the interior. In terms of market positioning, this case sits in the entry-to-mid tier. The inclusion of four ARGB fans and 360mm radiator support at this price point is a notable value proposition, making it attractive for budget-conscious builders who still want modern features.

E-ATX support also leaves room for future upgrades. * Enthusiasts planning high-end configurations: The 400mm GPU clearance and 360mm radiator support accommodate current flagship components, including custom water-cooling loops. * Creative professionals building a workstation: The spacious interior and cable management-friendly layout make it easier to install multiple storage drives and expansion cards without clutter. * Value-conscious users who want aesthetics: Four ARGB fans and a USB Type-C port at this price point are hard to beat, making it a great choice for those who want a good-looking build without overspending. ## Things to Consider Despite supporting E-ATX, the PONOS ULTRA MS4 is still a mid-tower case. Installing an E-ATX motherboard may reduce cable management space, so plan your routing carefully before assembly. The 165mm CPU cooler height limit means some of the largest air coolers, such as the Noctua NH-D15, may not fit. Always verify the cooler's height against this specification before purchasing. Compared to competitors in the same price range, the inclusion of a USB Type-C front port is a clear advantage, as many similarly priced cases omit it. However, if you need more drive bays or maximum expansion potential, a full-tower case would be a better fit. ## FAQ Q: Can I install an E-ATX motherboard in this case? A: Yes, the PONOS ULTRA MS4 supports E-ATX, ATX, Micro-ATX, and Mini-ITX motherboards. Q: Can I mount a 360mm radiator on both the front and top? A: Yes, the case supports radiators up to 360mm on both the front and top. Depending on where you mount the radiator, the internal layout will change, so plan your cooling configuration in advance. Q: Can the pre-installed ARGB fans sync with my motherboard? A: The included 120mm ARGB fans can be connected to your motherboard's ARGB header for synchronization.
