What was announced
TweakTown reports that Cooler Master introduced the MasterFrame 400 Mesh Gold Limited Edition compact chassis. The case is limited to 999 units worldwide, according to Vortez. The cooler is limited to 1,999 units, according to the Japanese outlet AKIBA PC Hotline and the Romanian site GetGeek. GetGeek adds that each cooler is individually numbered. Cooler Master's own page for the case calls it a limited edition but, in the text I could inspect, gives no unit count. Treat the quantities as press-reported.
Availability differs for each product, and TweakTown is the source for these details:
- Case: sold only inside complete META PCs systems. Preorders are open, with shipping expected in mid-November. Systems start at $4,899 and pair a Ryzen 7 9800X3D, the gold cooler, a GeForce RTX 5080 and 32GB of DDR5.
- Cooler: also sold inside META PCs systems, and sold on its own through Cooler Master for $199.99. Cooler Master's US liquid-cooling catalog lists the Gold Limited Edition at $199.99, which matches TweakTown.
If you only want the case, don't assume you can buy it separately in the US at launch. TweakTown says it is META-only.
The gold line has been in the works for a while. Cooler Master's own Computex 2026 post showed the COSMOS Alpha Gold, MasterFrame 400 Mesh Gold and MasterLiquid Atmos II Gold as limited-edition finishes.
MasterFrame 400 Mesh Gold: what builders need to know
This is the existing MasterFrame 400 Mesh in a new colour. It isn't a new chassis design. Cooler Master's page says it is built for Micro-ATX and Mini-ITX systems on the FreeForm 2.0 platform, with dual-orientation support.
Manufacturer-listed limits:
- GPU length: up to 390 mm
- CPU cooler height: up to 190 mm
- PSU: ATX or SFX, up to 160 mm long
- Cable space behind the tray: 43 mm
- Size: 471 × 261 × 373.8 mm including protrusions, or about 44 to 46 L depending on how it's measured
- Expansion slots: four
- Radiators: 240, 280 or 360 mm at the top, and 120 mm at the rear. The front and bottom have none.
- Fans: up to nine. A 140 mm, 30 mm-thick all-metal rear fan with gold blades comes preinstalled.
- I/O: two USB 3.2 Gen 1 Type-A ports, one USB 3.2 Gen 2x2 Type-C port and a combo audio jack
- Warranty: two years
Two limits are easy to miss:
- Storage and bottom fans are a trade-off. The single 3.5-inch and single 2.5-inch drive positions share mounting spots. Cooler Master says they are only supported without bottom fans.
- The PSU limit is tight. A 160 mm cap rules out many longer ATX units.
Some top-fan positions have conditions. The larger 180 and 200 mm options need fans no thicker than 25.5 mm. Check the full spec table before ordering fans.
MasterLiquid Atmos II Pro Gold
TweakTown describes a G9B V2 dual-chamber pump, three MasterFan A120 Gold fans with metal blades, and a 3D Mesh Gold pump cover. It has no RGB lighting or display. Supported sockets include LGA 1851, LGA 1700, AM5 and AM4. Cooler Master's page also lists older Intel sockets, including LGA 1200, 1150, 1151, 1155 and 1156.
- Radiator: 394 × 119.2 × 27 mm. This is longer than the nominal "360 mm" label suggests, so check clearance in your case.
- Pump: rated at 3,400 ± 300 RPM and up to 25 dB(A)
- Fans: 0 to 2,300 RPM ±10%, up to 80.69 CFM, 6.1 mmH₂O static pressure and up to 29.7 dB(A)
- Covers: a 3D Mesh Gold cover, a metallic cover and a VRM fan cover. Per GetGeek, the magnetic covers can be swapped without removing the whole cooler.
- Warranty: six years, per Cooler Master's page
Cooler Master claims the optional VRM fan cover can cut temperatures around the motherboard's power delivery by up to 13°C. That is a manufacturer test claim, and the page gives no test setup. Cooler Master's page also gives two sets of fan numbers: 2,500 RPM and about 27 dB(A) in the marketing text, against 2,300 RPM and 29.7 dB(A) in the spec table. I used the spec table.
Does the case fit the cooler?
Probably, but check your motherboard layout. The top mount allows radiators up to 360 mm. The Atmos II Pro's 394 mm radiator is the kind of part where a few millimetres can matter, so check it against your RAM height and motherboard layout before you buy. I haven't tested this combination, and neither TweakTown nor Cooler Master addresses it directly.
Bottom line
For builders, the useful information is that the case's specs match the standard MasterFrame 400 Mesh. The cooler is a mainstream AIO with a gold finish and swappable covers. If you want the look, the cooler is the easy buy at $199.99. The case, for now, means buying a $4,899-and-up META system. The prices, preorder terms and mid-November ship date come from TweakTown, not from Cooler Master's pages.
