It suits people who want a gaming PC with a near full-size graphics card in a much smaller footprint than an ATX case. It does not suit people who care most about expandability or an easy build. It holds roughly 18 liters, measures 185 mm wide, 292 mm tall and 376 mm deep, and ships with two side panels: one tempered glass and one vented steel. You can switch between looks and airflow even after the build is done. Since it came out in 2020, the NR200P has been a common first case for small form factor (SFF) builders. On Amazon. co. It fits triple-slot GPUs up to 330 mm long, radiators up to 280 mm and up to seven fans. A PCIe riser cable is included for mounting the GPU vertically. ## Compatibility Guide With a small case, the most important question is whether your parts will fit. The table below lists the limits from the provided specs that most often cause problems. | Item | Supported | What to check | |---|---|---| | Motherboard | Mini-ITX only | Micro-ATX and ATX will not fit | | Power supply | SFX / SFX-L | Standard ATX PSUs will not fit | | GPU length | Up to 330 mm | Check thickness (slot count) too | | CPU cooler height | Up to 155 mm | Leave a few mm of margin | | Radiator | Up to 280 mm | 360 mm is not supported | | Fans | Up to 7 | GPU thickness changes which positions you can use | | Internal bays | 7 total (per spec data) | Not built for many 3.5-inch HDDs | The power supply is where most builds go wrong. The NR200P only takes SFX or SFX-L units, so you cannot reuse an ATX PSU. SFX units cost more than ATX units of the same wattage and there are fewer to choose from, so budget for the PSU as well as the case. SFX-L units are longer, which makes cable routing tighter. If you plan to use a power-hungry GPU, buy an SFX unit with spare wattage. The 330 mm figure is a length limit. For thickness, plan on triple-slot at most: a card thicker than three slots may not fit even if its length does. A thicker GPU also leaves less room for fans or a radiator on the side panel. Check your card's length, thickness and power connector position before you buy. CPU coolers up to 155 mm tall are supported. In a small case, a cooler that almost touches the side panel can choke its own air intake, so leave a few millimeters of margin. Also check that tall memory heatsinks do not hit the cooler. AIO coolers are supported up to 280 mm, but the supported size can depend on the mounting position. Check the manual for what each position accepts. A radiator plus its fans can be thick enough to hit the GPU or motherboard parts. A 360 mm AIO will not fit. The included riser is a PCIe 3.0 cable. If a PCIe 4.0 or newer GPU gives a black screen or runs unstably when mounted vertically, the usual fix is to set the slot to Gen3 in the BIOS. The gaming performance difference at PCIe 3.0 is generally reported as small, but it is not zero. ## Product Info The NR200P is made by Cooler Master and is listed as a mini-tower case. It is built from powder-coated steel (listed as alloy steel in the spec sheet) and tempered glass, and it supports both air and liquid cooling. The spec data lists the weight as 5.93 kg, and it gets heavier once your parts are installed, so keep that in mind if you plan to move it often. The two side panels serve different purposes. The glass panel shows off the inside, while the vented steel panel lets in more air and keeps temperatures down. For a hot CPU and GPU, a sensible approach is to build with the vented panel first and switch to glass only if temperatures leave room. Pricing: as of May 20, 2026, the Amazon. co. That listing is sold and shipped by a third-party seller, not by Cooler Master, so it may differ from authorized retail pricing, and it is high for a Mini-ITX case. Prices change often, so compare several retailers and check the current price on the product page. Overseas marketplace listings vary widely in price and add shipping and import costs. ## Build Tips Every panel on the NR200P, including the frame panels, comes off without tools, so you can reach the inside from all sides. Building it like an ATX case still leads to dead ends. - Mount the CPU, memory, M.2 SSD and CPU cooler on the motherboard before it goes into the case - Plug only the cables you need into the PSU before you install it (a modular PSU helps a lot) - Connect the front-panel headers and CPU power before installing the GPU - Install the GPU last and make sure its power cables are not sharply bent Spare cable length easily blocks airflow in a small case. Tidying cables away from the GPU intake alone can lower temperatures. ## Competitor Comparison Competing SFF cases include the Fractal Design Terra and the Lian Li Q58. The Terra is even smaller and aimed at buyers who care about the look and feel of materials. The Q58 takes a different approach to design and power supply options. Both support a different range of parts than the NR200P, so check that your GPU and cooler fit each one before comparing. | Point | NR200P | Typical ATX mid-tower | |---|---|---| | Motherboard | Mini-ITX only | ATX, Micro-ATX, Mini-ITX | | Power supply | SFX / SFX-L | ATX (cheaper, more choice) | | Radiator | Up to 280 mm | Often 360 mm | | Footprint | Small | Large | | Ease of build | Needs a planned build order | Roomy, beginner-friendly | If small size is not a must, and you want a 360 mm AIO or plan to reuse an ATX PSU, a mid-tower will cost less overall and take less effort. ## Best Use Cases - **Gamers short on desk or floor space**: GPUs up to 330 mm and 280 mm radiators fit, which covers mid-range to high-end builds. - **Builders who want to choose between looks and airflow later**: both panels are included, so you can decide after checking temperatures. - **First-time SFF builders**: tool-free panels and access from all sides make it one of the easier small cases, though it still takes more planning than a mid-tower. - **Vertical GPU showcases**: the riser cable is in the box, so you do not need to buy one separately. ## Things to Consider **The case is not the only extra cost. ** You also need an SFX PSU and a Mini-ITX motherboard, and Mini-ITX boards usually cost more than ATX boards with the same chipset. Expect a higher total budget than an ATX build. **A GPU can be short enough and still too thick to fit. ** Be careful with cards thicker than three slots. A thick GPU also leaves less room for extra fans on the side panel. **The glass panel can make a hot build run hot. ** A small case holds little air, and the glass panel restricts intake. If you use a high-wattage GPU, plan around the vented panel. **It is not built for lots of storage. ** If you want several large 3.5-inch HDDs for data storage, a mid-tower is easier. **Check the listing price. ** As noted above, the Amazon listing at the time was from a third-party seller and was high for this type of case. Check who the seller is and compare with other retailers. Listing details can also contain errors, so use the photos and title to confirm it is the NR200P (the version with the glass panel and riser). **Who should skip it:** anyone who wants to reuse an ATX PSU, use a 360 mm AIO, or get a first build done without dealing with cable routing will probably be happier with a mid-tower. ## FAQ **Q. Can I use an ATX power supply? ** A. No. Only SFX and SFX-L units fit. **Q. Will a large high-end GPU fit? ** A. Yes, if it is no longer than 330 mm and no thicker than three slots. Card sizes vary by manufacturer even for the same GPU chip, and some exceed three slots or 330 mm. Check the dimensions for your exact model. **Q. Can I use an AIO liquid cooler? ** A. Yes, with radiators up to 280 mm. A 360 mm radiator will not fit. Check the manual for the size each mounting position accepts. **Q. Glass panel or vented panel? ** A. Choose the vented panel for lower temperatures and the glass panel for looks. For a hot build, start with the vented panel. **Q. How is the NR200P different from the NR200? ** A. The NR200P adds a tempered glass side panel and a PCIe riser for vertical GPU mounting. The core chassis design is the same. ### Product Disclosure (Amazon) - Manufacturer: Cooler Master - Seller: ララグランダム - Fulfilled by: ララグランダム - ASIN: B08BDWSTG1 - Note: This article covers a manufacturer-made product based on Amazon listing details.
