This article covers CORSAIR 4000D RS ARGB ホワイト モジュール式 PC ケース.

Overview

The CORSAIR 4000D RS ARGB White is a mid-tower ATX case that takes the proven airflow foundation of the 4000D series and adds a modular twist. The standout feature is the FRAME system, which lets you swap out components like the motherboard tray and front I/O panel for future customization—something rarely seen in this price bracket. Out of the box, you get three RS120 ARGB fans pre-installed at the front, delivering excellent lighting and airflow right away. Cooling potential is serious for a case of this size. You can install up to twelve 120mm fans, dual 360mm radiators simultaneously, and even a 200mm fan in the front thanks to the InfiniRail mounting system. CPU cooler clearance is 170mm, GPU clearance is 370mm, and PSU clearance is 180mm, so high-end parts fit without compromise. The white finish with a tempered glass side panel looks clean and modern. It also supports back-connector motherboards from ASUS (BTF), MSI (Project Zero), and Gigabyte (Project Stealth), making cable management almost invisible. This is a strong candidate for anyone building a clean-looking high-performance PC.

Compatibility Guide

Motherboard support spans E-ATX (up to 305×277mm), ATX, Micro-ATX, and Mini-ITX. Back-connector boards (ASUS BTF, MSI Project Zero, Gigabyte Project Stealth) are explicitly compatible, which is still rare for mid-tower cases. PSU: Standard ATX, bottom-mount, up to 180mm long. Cooling clearance: CPU cooler 170mm max, GPU 370mm max, PSU 180mm max. Radiator support: Front, top, and side each accept 360/280/240mm. Rear takes 140/120mm. Dual 360mm radiators are possible. Fan support: Up to 12x 120mm, or mixed sizes via InfiniRail (200/140mm front). Drive bays: 2x 3.5-inch or 4x 2.5-inch. Expansion slots: 7 horizontal + 4 vertical. * Dust filters: Front, bottom, and side included.

Product Info

The CORSAIR 4000D RS ARGB White (model CC-9011297-WW) launched in late 2024 with an approximate street price of ¥15,000–¥16,000 in Japan. It carries the standard two-year manufacturer warranty. This case sits in the upper-mid tier of the market. It offers modularity and back-connector support that you'd normally find only in premium cases, while keeping the base price affordable. The included triple RS120 ARGB fans add significant value for anyone wanting a colorful build without extra fan purchases.

Best Use Cases

Gaming PC Builders — The triple ARGB fans and support for up to 12 fans total make it easy to create a vibrant gaming rig. Dual 360mm radiator support means you can cool even a top-tier CPU and GPU with liquid cooling. Back-connector motherboard support helps hide cables for a clean, professional look. Upgrade Enthusiasts — The FRAME modular system lets you replace the motherboard tray or front I/O later if standards change. This future-proofing is rare at this price and makes the case a long-term investment. * White Theme Builders — If you're aiming for an all-white system, this case provides a solid foundation. The white steel body, glass panel, and white ARGB fans create a cohesive aesthetic that's hard to achieve with black cases.

Things to Consider

While the 4000D RS is spacious for a mid-tower, full-tower cases offer more room for custom loops or massive radiators. E-ATX boards will fit, but cable management behind the tray can get tight depending on your PSU and drives. Back-connector motherboard compatibility is limited to ASUS BTF, MSI Project Zero, and Gigabyte Project Stealth. Other brands with reversed connectors are not supported, so verify your board before buying. The included fans are 120mm only; if you prefer 140mm fans for lower noise, you'll need to buy them separately. The iCUE LINK system hub is also sold separately—without it, fan RGB control is still possible via the case's built-in controller, but iCUE LINK simplifies wiring significantly. Weighing about 8.2kg (18 lbs), the case is fairly heavy. The tempered glass side panel is beautiful but requires careful handling during component swaps. ## Alternatives
Direct competitors in the same ¥12,000–¥16,000 range include the NZXT H7 Flow (approx ¥16,000) and Fractal Design Pop Air (approx ¥12,000). The H7 Flow comes with four standard fans and a cleaner exterior, but lacks modularity and back-connector support. The Pop Air is more affordable and still good for airflow, but has no RGB fans and fewer fan mounting positions. The 4000D RS ARGB differentiates itself with its FRAME modular system, back-connector compatibility, and out-of-the-box RGB. For builders who want a case that can evolve with their hardware, it offers unusual flexibility at a reasonable price.
