Corsair has released a new Corsair blush pink PC case option across two of its most popular Frame-series models, the Frame 4000D RS II ARGB and the 3500X RS-R ARGB. The pink finish is available now in the United States, and Corsair says it will reach the UK, Europe and other regions by December.

Both cases keep their existing layouts, panel systems and airflow designs. Only the colour changes, giving builders a softer alternative to the black and white finishes that have dominated the market for years. Corsair has also bundled four pre-installed ARGB fans with each pink model, so neither case needs extra cooling hardware bought separately to look the part out of the box.

What comes with the Corsair blush pink PC case lineup
The Frame 4000D RS II ARGB is the airflow-focused option of the pair. It supports up to 13 120mm fans, dual 360mm radiators and reverse-connector motherboards, making it a flexible base for anything from a quiet office build to a heavily cooled gaming rig. Corsair’s modular FRAME system carries over unchanged, letting owners swap panels and internal components to reshape the case without buying a new chassis.
The 3500X RS-R ARGB takes a different approach. It pairs the new blush pink shell with wraparound tempered-glass panels for a more showcase-style build, while still supporting back-connect motherboards for cleaner cable routing. A built-in GPU anti-sag arm is included to stop heavier graphics cards from drooping over time, and the case accepts radiators up to 360mm.
Frame 4000D RS II ARGB versus 3500X RS-R ARGB
Both cases share the same pink finish and four-fan bundle, but they’re built for slightly different priorities. The table below breaks down the key differences for anyone deciding between the two.
| Feature | Frame 4000D RS II ARGB | 3500X RS-R ARGB |
|---|---|---|
| Design focus | Maximum airflow and modularity | Showcase build with wraparound glass |
| Fan support | Up to 13x 120mm fans | Four pre-installed fans standard |
| Radiator support | Dual 360mm radiators | Up to 360mm |
| Motherboard support | Reverse-connector compatible | Back-connect compatible |
| Extra feature | Swappable FRAME panel system | Built-in GPU anti-sag arm |
Where the new colourway is landing first
US buyers get first access to the new finish, with both the Frame 4000D RS II ARGB and 3500X RS-R ARGB already listed in that market. Corsair has confirmed the blush pink versions will expand to the UK, Europe and other regions by December, though it hasn’t detailed an exact rollout date for each territory beyond that window.
This staggered release pattern isn’t unusual for case manufacturers, who often prioritise their largest market before scaling production and distribution for secondary regions. Builders outside the US who want the pink finish will simply need to wait a little longer than their American counterparts.
Why a pink finish stands out in a crowded case market
Case colour options have expanded steadily over the past few years, but black and white still account for the overwhelming majority of sales. Pink remains a niche choice, used mostly by boutique brands or limited runs rather than a manufacturer’s mainstream lineup. Corsair putting the colour across two of its higher-volume Frame models signals growing confidence that demand for distinctive-looking builds extends beyond the usual RGB-heavy aesthetic.
For buyers, the appeal goes beyond looks. Because both pink cases retain the exact feature set of their standard-colour siblings, including the Frame 4000X RS relatives and the larger Frame 5000D RS ARGB in the same family, there’s no trade-off for choosing the new colour. Builders get the same airflow, radiator support and modularity as the existing black and white models, just with a finish that’s harder to find elsewhere.
Corsair has also previously explored alternative finishes in the Frame range, including Corsair’s wood-panelled Frame 4000D variant, suggesting the company sees cosmetic variety as a genuine growth area rather than a one-off experiment. Full specifications and regional availability updates are typically posted through Corsair‘s own channels as new colourways reach additional markets, and shoppers can check its case lineup directly for current listings.
