It suits two kinds of builders: people who want a back-connect motherboard with hidden cables, and people planning a serious liquid-cooling setup with two 360mm radiators. For them, it leaves a lot of room to grow at a relatively accessible price. If you are only building a conventional air-cooled gaming PC with a mid-range graphics card, most of that flexibility will go unused. Its FRAME design lets you swap the motherboard tray and front I/O panel to suit your layout. Three RS120 120mm fans come pre-installed at the front, and the case supports up to twelve 120mm fans or two 200mm fans. It also supports back-connect motherboards: ASUS BTF, MSI Project Zero and Gigabyte Project Stealth. ## Where It Fits The 4000D name also appears on CORSAIR's long-running conventional mid-towers, such as the iCUE 4000D RGB AIRFLOW, but the FRAME 4000D RS follows a different idea. The older models are finished boxes you buy as-is. The FRAME 4000D RS is built to be reconfigured after purchase. Because the names are similar and often appear side by side in search results, check the product name and ASIN (B0DPJ9K8WK) on the listing before you buy. As the high-airflow name suggests, the three front intake fans are ready out of the box. They are front intake fans only, though, so any top or rear exhaust fans are yours to add. Twelve fans is the maximum the case can hold, not the number in the box. Keep that in mind when you budget. ## Compatibility Guide | Item | Support | |---|---| | Motherboard | ATX / Micro-ATX / Mini-ITX | | Back-connect | ASUS BTF / MSI Project Zero / Gigabyte Project Stealth | | PSU | Standard ATX, bottom mount | | Fans | Up to 12x 120mm or 2x 200mm | | Radiators | Up to 2x 360mm (top and front) | **Motherboards**: ATX, Micro-ATX and Mini-ITX are supported. E-ATX is not on the list, so check the official compatibility chart before choosing a wide E-ATX board. Conventional front-connect boards work fine, so you can start with a standard board and move to a back-connect one on a later rebuild. **Back-connect boards**: ASUS, MSI and Gigabyte each take their own approach to connector placement. Even though the case supports all three standards, confirm that your exact board model lines up with the case cutouts. This matters most for newly released boards, which can take a while to appear on compatibility lists. **Radiators and GPUs**: You can mount a 360mm radiator at the top and another at the front at the same time. A top radiator with fans can collide with tall memory heatsinks or VRM heatsinks, and a front radiator eats into GPU clearance. Maximum GPU length and CPU cooler height are not included in the data behind this article, so check the official product page if you plan to use a large high-end GPU or a tall air cooler. **Fan headers**: Most motherboards do not have enough fan headers for twelve fans. You will need splitters, a fan hub, or the iCUE LINK System Hub (sold separately) if you go the iCUE LINK route. Decide early where each fan will connect and what will control it. **PSU**: The PSU mounts at the bottom and takes a standard ATX unit. With a long, high-wattage PSU there is less room to bend cables, so a modular PSU makes rear cable management easier. ## Product Info | Item | Detail | |---|---| | Motherboard support | ATX, Micro-ATX, Mini-ITX | | Material | Steel, tempered glass | | Weight | 8.2 kg | | Included fans | 3x RS120 120mm | | Max fans | 12x 120mm or 2x 200mm | | Radiators | Up to 2x 360mm (top, front) | | iCUE LINK | Supported (hub sold separately) | | PSU mount | Bottom | | Color | Black | On Amazon. co. Check the retailer's page for the latest price. That is accessible for a modular case with back-connect support, but prices move with sales and stock, so check the listing for the current figure. Condition and shipping vary by listing, so factor those in when you compare. That is a reasonably large sample, and overall reception among DIY builders is strong. The case weighs about 8.2 kg and has a tempered glass side panel. The iCUE LINK System Hub is sold separately, so budget for it if you want iCUE LINK to handle wiring and control. ## Planning Your Build This case gives you a lot of freedom, and that makes it easy to get stuck mid-build without a plan. 1. **Cooling**: air, one AIO, or two radiators. Radiator placement decides fan direction and your GPU length limit. 2. **Motherboard type**: back-connect or conventional. If back-connect, confirm compatibility first. 3. **Fan count and control**: stay with the three included fans or add exhaust, and decide which headers or hub each fan uses. At 8.2 kg empty, the finished build will be heavy. Pick its final spot in advance, and remove the glass panel and set it somewhere safe while you work. ## Compared With Alternatives CORSAIR's own iCUE 4000D RGB AIRFLOW and iCUE 4000X RGB come with fans and lighting already in place. If you want a good-looking PC right away and have no plans to rebuild, they are the simpler choice. The FRAME 4000D RS favors future expansion and rebuilding over that. If back-connect is your main goal, a Project Zero case such as the MSI MAG PANO M100R PZ is also worth a look. If you are committed to one board brand, a case from the same brand can make compatibility easier to confirm. Because the FRAME 4000D RS supports all three standards, it suits builders who have not chosen a board brand yet or may switch later. If silence matters most, compare it with a quieter case such as the be quiet! Pure Base 501. High-airflow cases cool well, but they also let more fan noise out. ## Best Use Cases - **Back-connect builders**: ASUS BTF, MSI Project Zero and Gigabyte Project Stealth support make an almost cable-free look possible. - **Custom-loop gamers and creators**: Support for two 360mm radiators allows builds that liquid-cool both the CPU and GPU. - **Long-term upgraders**: The FRAME design lets you swap the motherboard tray and front I/O later, so moving from air to liquid cooling is straightforward. - **Value-focused enthusiasts**: At the observed price point, it covers an unusually wide range of features. ## Things to Consider **Not for compact builds. ** It is a mid-tower, but it is designed to hold twelve fans or two 360mm radiators, so it is not small. Measure your desk space first. **Twelve fans is a maximum, not the bundle. ** Only three RS120 fans are included. Adding exhaust fans or building a dual-radiator setup means paying for more fans and a hub on top of the case. **Check the lighting if you want RGB. ** The data behind this article does not confirm whether the RS120 fans bundled with this RS model have lighting. If you want a lit build, check the listing to confirm which variant you are buying. **Back-connect boards are still limited. ** They come in fewer models and usually cost more than standard boards with the same chipset. If back-connect is your reason for buying, make sure the board you want is actually available. **Confirm GPU length and cooler height. ** These figures are not in our data. A front radiator reduces GPU clearance further. **Watch for similarly named models. ** Several cases carry the 4000D name. The price panel on this site can also show a Japanese Amazon price in a slot labeled as an overseas store. Before buying, use the images, product name and ASIN to confirm you have the right product. **Airflow comes at some cost to noise. ** More open intake means more audible fans. For a bedroom or quiet office, lower the fan curves or consider quieter fans. ## FAQ **Q. Does it work with a normal (non back-connect) motherboard? ** A. Yes. Standard ATX, Micro-ATX and Mini-ITX boards are supported. Back-connect support is an option, not a requirement. **Q. Are the included fans enough? ** A. The three included fans are front intakes. With a power-hungry CPU or GPU, add top or rear exhaust fans to keep heat from building up. **Q. Do I need the iCUE LINK System Hub? ** A. No, the case works without it. The hub is sold separately and is only needed if you want iCUE LINK to handle wiring and control. **Q. Where can a 360mm AIO go? ** A. At the top and the front, with up to two installed at once. At the top, watch for clashes with memory and VRM heatsinks. **Q. Will a large graphics card fit? ** A. Maximum GPU length is not in our data, so check the official product page. A front radiator reduces the available length. ### Product Disclosure (Amazon) - Manufacturer: CORSAIR - Seller: Amazon.co.jp - Fulfilled by: Amazon.co.jp - ASIN: B0DPJ9K8WK - Note: This article covers a manufacturer-made product based on Amazon listing details.
