Compatibility — check before buying:
Exact variant: MF600-SGNN-S00 is the Silver model with four preinstalled SickleFlow ARGB fans. The Black model, MF600-KGNN-S00, uses non-ARGB Mobius fans and must not be confused with this configuration. Motherboard support: Mini-ITX, Mini-DTX, Micro-ATX and ATX are listed, with conditional support for E-ATX and SSI-CEB motherboards. Check the exact board dimensions and installation requirements. Cooling: a 420mm front radiator is subject to a 458mm length limit. A 420mm top radiator requires relocating the I/O module to the front panel. Component clearance: graphics-card length up to 485mm including the power connector, graphics-card height up to 190mm including the connector, CPU cooler height up to 190mm and ATX PSU length up to 235mm. The power supply, motherboard, graphics card and optional radiators are not included.

Key Features
FreeForm 2.0 modular chassis architecture
The MasterFrame 600 uses Cooler Master's FreeForm 2.0 modular design platform. Its exposed structural frame, interchangeable exterior elements and accessible modular design resources give enthusiasts opportunities to personalise their PC case. Optional decorative panels and additional modifications depend on accessory availability and compatibility; they are not all included with the standard enclosure.
Four preinstalled SickleFlow ARGB fans
The Silver variant includes three SickleFlow ARGB 140mm fans at the front and one SickleFlow ARGB 120mm fan at the rear. All four provide addressable RGB lighting, distinguishing this configuration from the Black model with non-illuminated Mobius fans. The supplied ARGB/PWM hub helps organise the fan and lighting connections.
Extensive 420mm radiator compatibility
Radiators up to 420mm can be installed at the front, side or top, subject to the specific mounting restrictions. The front allows radiator lengths up to 458mm, while a top-mounted 420mm radiator requires moving the I/O module to the front panel. A 120mm radiator can also be installed at the rear. Check complete radiator dimensions and interference with other components before installation.
Large-component compatibility
The case supports graphics cards up to 485mm long, including the power connector, and up to 190mm high, including the connector. CPU air coolers up to 190mm high and ATX power supplies up to 235mm long are supported. Conditional E-ATX and SSI-CEB motherboard compatibility provides further configuration options when the exact board dimensions and layout meet the installation requirements.
Aluminium frame detailing and tempered glass
The chassis combines SGCC steel with aluminium exterior elements, complemented by a tempered-glass panel and contrasting aluminium side construction. Its exposed-frame appearance highlights the modular structure. Tool-free panel removal simplifies access during assembly, maintenance or subsequent modifications.
USB-C 20Gbps and practical installation features
External connectivity includes one USB 3.2 Gen 2x2 Type-C port rated at 20Gbps, two USB 3.2 Gen 1 Type-A ports and a combined headset jack. The chassis provides 43mm of cable-routing space behind the motherboard tray, dust filters at multiple positions and an included graphics-card support bracket. Full USB-C performance requires a compatible motherboard connection and attached device.

Frequently Asked Questions
How many ARGB fans are included with the MasterFrame 600 Silver?
Four SickleFlow ARGB fans are preinstalled: three 140mm fans at the front and one 120mm fan at the rear. The silver variant also includes an ARGB/PWM hub. The black variant uses a different, non-ARGB Mobius fan configuration.
What is FreeForm 2.0?
FreeForm 2.0 is Cooler Master's modular chassis design platform. The MasterFrame 600 uses an exposed structural frame and interchangeable panel concept, allowing greater freedom to modify the case's appearance and configuration. Optional replacement panels and custom components are not necessarily included with the standard retail package.
Can I install a 420mm liquid-cooling radiator?
Yes. The front, top and side radiator positions support up to 420mm. The front radiator must fit within a 458mm overall length limit. Installing a 420mm radiator at the top requires moving the I/O module to the front panel. Check all radiator and fan dimensions before installation.
Does it support E-ATX and SSI-CEB motherboards?
Cooler Master lists both E-ATX and SSI-CEB with conditional support. Mini-ITX, Mini-DTX, Micro-ATX and ATX are also listed. Because the two larger standards have installation conditions, verify your exact motherboard dimensions, mounting arrangement and cable clearances before purchasing.
What is the maximum supported graphics-card size?
The manufacturer specifies graphics-card clearance up to 485mm in length and 190mm in height, including the power connector. Check the overall dimensions of the specific graphics card, including its power cabling and any cooling hardware nearby.
Does the case include a graphics-card support bracket?
Yes. Cooler Master lists a GPU support bracket in the package contents for the MasterFrame 600 Silver. It is intended to provide additional support for installed graphics cards and help reduce sag.
Does the case support USB-C 20Gbps?
The external USB Type-C connection is specified as USB 3.2 Gen 2x2, supporting a theoretical transfer rate of up to 20Gbps. Full operation depends on a compatible internal motherboard USB header and a connected device supporting the required interface.
Is a power supply included?
No. The MasterFrame 600 Silver is supplied without a power supply. It supports ATX power supplies up to 235mm long. Select a compatible PSU separately according to your system's electrical and physical requirements.
Singular Expert Insight
The most important distinction when selecting the Cooler Master MasterFrame 600 Silver is that it is not simply the black model in another colour. The silver MF600-SGNN-S00 includes four illuminated SickleFlow ARGB fans and an ARGB/PWM hub, whereas the black MF600-KGNN-S00 uses non-ARGB Mobius cooling fans. That difference directly affects the included equipment and overall appearance. Beyond the fan package, the MasterFrame 600 stands out for its FreeForm 2.0 modular structure and exposed aluminium-and-steel frame. It is particularly suitable for builders who value the ability to customise a chassis rather than work within a completely fixed enclosure. The cooling options are extensive, with 420mm radiator positions at the front, top and side, but they are subject to practical mounting conditions. In particular, the top 420mm installation requires relocation of the I/O module, and the front radiator has a 458mm length limit. Large graphics cards also require careful clearance checks, including the power connector. The supplied GPU support bracket, generous 43mm cable-routing space and modular panel access add practical value during assembly. Choose this version when its silver appearance, four factory-installed ARGB fans and modular design are central to your planned PC build.
Buyer's Guide
Buy it if
You want a modular silver PC case with four included SickleFlow ARGB fans, aluminium exterior elements, tempered glass, large graphics-card clearance and flexible cooling options.
Skip it if
You need a compact enclosure, require unconditional compatibility with a particular E-ATX or SSI-CEB motherboard, or prefer a case without illuminated cooling fans.
Also consider
The Cooler Master MasterFrame 600 Black (MF600-KGNN-S00) if you prefer non-ARGB Mobius fans, or compare other MasterFrame configurations if your build needs a different form factor or exterior design.
