AI Verdict
The Cooler Master NR200 is an 18-liter steel ITX case built for first-time small form factor builders who want to fit a 330mm GPU without spending over $100.
At 18.25 liters, the NR200 provides enough internal volume to house a 330mm triple-slot GPU and a 280mm side radiator simultaneously. The fully modular frame and tool-less panels remove the typical frustrations of building in a sub-20L chassis. It perfectly bridges the gap between massive ATX towers and ultra-cramped 10L boutique cases.
If you want to vertically mount your GPU and show off your parts, upgrade to the NR200P which includes a PCIe riser cable and a tempered glass side panel.

Pros
- Fits massive 330mm triple-slot GPUs like the RTX 4090 or RX 7900 XTX.
- Tool-less side panels use a dual-peg system that pops off in seconds.
- Supports 240mm or 280mm side-mounted radiators for liquid cooling.
- Includes 3D printing templates for custom feet and ATX power supply brackets.
- Fits 155mm tall air coolers, with users reporting up to 158mm clearance for models like the Scythe Fuma 2.
Cons
- Using an SFX-L power supply blocks the top-front 120mm exhaust fan mount.
- Cable management space behind the motherboard tray is non-existent, forcing you to route cables behind the PSU or GPU.
- The included 92mm rear and 120mm top SickleFlow fans use proprietary rubber friction pegs that can pop loose during shipping.
- Side-vented exhaust means you will feel a constant warm breeze if the case sits on the right side of your desk.
Dimension Scores
Unrestricted mesh side panels and bottom intakes keep 300W+ GPUs well under 70°C.
The open mesh design lets internal fan noise escape easily, requiring custom fan curves for silent operation.
The all-steel frame is rigid, and the dual-peg tool-less panels snap into place securely.
Zero routing space behind the motherboard tray forces you to stuff excess cables behind the power supply shroud.
Best For
- First-time small form factor builders moving down from a mid-tower ATX case.
- Air-cooled setups utilizing a 155mm tower cooler and two bottom intake fans.
- Budget-conscious ITX builds where the $50-$90 price leaves room for a better GPU.
Not Recommended For
- Showpiece RGB builds, since the vented steel side panel hides all internal components.
- Builders who want to reuse their standard ATX power supply without relying on zip-ties or 3D printed brackets.
Watch Out For
- The front panel audio cable is extremely short, forcing you to stretch it tight across the motherboard to reach rear-mounted headers.
- Mounting a 280mm AIO on the side bracket makes routing the stiff pump tubes incredibly difficult without hitting the top fans.
- The power supply extension cable routes directly over the 8-pin CPU power plug, making it hard to plug in unless you remove the top panel.
- The included top fans use a tool-less push-pin mounting system that cannot support the weight of a top-mounted radiator.

What Buyers Say
Cooler Master nailed the $50-$90 price point by offering a fully modular frame that strips down to its bare skeleton. Component installation takes half the time of a standard ITX build because you can access the motherboard from all 360 degrees. Cable management is the biggest hurdle. The lack of space behind the motherboard tray forces you to stuff excess wires behind the power supply shroud. The side and bottom mesh panels feed direct fresh air to the CPU and GPU, keeping 300W+ graphics cards under 70°C.
“I crammed a 5800X3D and a massive RTX 3080 in here and my temps are actually better than my old mid tower, just buy some zip ties because hiding the cables is a nightmare.”
Common Praise
- The frame can be completely disassembled, making it easy to plug in cables before putting the shell back on.
- Fits massive 330mm graphics cards without requiring a PCIe riser cable.
- The tool-less side panels pop off instantly without needing thumbscrews.
- Bottom fan mounts feed cold air directly into the GPU intake fans.
Common Complaints
- No cable routing space behind the motherboard tray.
- The included SickleFlow fans use annoying rubber mounting pins instead of standard screws.
- Using an SFX-L power supply blocks the top fan mount above it.
- The front panel audio cable is too short for motherboards with rear-mounted audio headers.
Ownership Tips
- The rubber friction pegs holding the top fans will degrade over time if you remove them frequently.
- Dust buildup is noticeable after a few months because the magnetic dust filters are standard mesh, not high-density.
- If you keep the PC on the right side of your desk, the side exhaust will constantly blow warm air onto your mouse hand.
Frequently Asked Questions
Can I fit an ATX power supply in this case?
Out of the box, no. You must either 3D print Cooler Master's official ATX bracket, buy a third-party bracket on Etsy, or use zip-ties to secure it to the front panel.
Will a Noctua NH-U12A or Scythe Fuma 2 fit?
The official spec sheet lists a 155mm maximum CPU cooler height. The 154.5mm Scythe Fuma 2 fits perfectly, but the 158mm Noctua NH-U12A will press against the vented side panel.
Can I mount a radiator at the bottom?
Yes, but it is highly discouraged unless you are doing a custom water cooling loop. Mounting an AIO radiator at the bottom puts the pump at the highest point, trapping air and killing the pump.
Do I need to buy extra fans?
The case includes one 120mm top exhaust and one 92mm rear exhaust fan. Adding two 120mm slim fans at the bottom as intake significantly drops GPU temperatures.
Can I fit a 3-slot RTX 4090 or 5090?
Yes, the case supports GPUs up to 330mm long and 156mm tall. Users have successfully fit massive cards like the PNY RTX 4090 and Founders Edition models.
Is the front panel mesh for airflow?
No, the front panel is solid steel. All intake air comes from the vented side panels and the bottom of the case.
Buying Guide
Building a small form factor PC requires strict attention to component dimensions. You cannot just buy parts and hope they fit. You must verify your graphics card length is under 330mm and your CPU air cooler is under 155mm tall. Because this case relies on an SFX power supply, you will pay a premium for your PSU compared to standard ATX models. Plan your cable routing before you screw the motherboard in, as space is extremely tight.
18.25L Volume
Liters measure the total internal space of the case. At 18 liters, this is about the size of a large shoebox—half the size of a standard desktop, but twice the size of ultra-compact console-style cases.
SFX PSU Support
SFX power supplies are physically smaller than standard ATX power supplies. They cost more, but they leave crucial empty space inside the case for cable management and airflow.
330mm GPU Clearance
This dictates the maximum length of your graphics card. 330mm is long enough to fit most high-end triple-fan coolers, meaning you don't have to buy a special 'mini' graphics card.
Alternatives
If you want a smaller footprint on your desk, look for a vertical 'tower' style ITX case with a sub-15L volume. If you want to reuse your standard ATX power supply and micro-ATX motherboard, look for a 22L-25L compact mid-tower.
