LAS VEGAS--Corsair has revamped one of its most popular PC cases into a new, more customizable design. The Corsair Frame 4000D is reminiscent of the company’s original 4000D PC case we reviewed not long back, but it has far more interesting front and side panels, and a whole bunch of future potential. In time, this case should give you copious options to customize a PC build through accessories and fan-mounting flexibility.

The real stars are these customization options. The Frame 4000D's swappable panels, flexible mounting rails, and interesting inserts make it a DIY system builder’s potential dream case. Have a look at the video above for more; we've got a deeper rundown below, too.


A Base Frame to Customize

Right off the shelf, the Frame 4000D is a snazzy-looking ATX form factor case with a unique front panel. We very much like the design of the face, which is punched through with twists of metal in a wavy Y-shaped pattern, very unlike any other case face we've seen.

Corsair sells three basic configurations of the Frame: For $94.99, you can get a base model in black or white without any fans. Up that to $99.99, and you’ll get three non-RGB fans; for $109.99, those three fans will come with RGB LEDs.

It’s a quality case, but stop there, and you’d think this is still just any old ATX box. The most remarkable aspects of this case might come in the future, assuming Corsair starts shipping some of the optional accessories it showed in early form at CES. The front panel is slick, and, mind you, we'd be hesitant to swap it out, but you have four alternate front panels to choose from. In addition to the standard one, Corsair has metal and glass options, one that looks like wood, and another prototype with a more aggressive, edgy look with RGB LED lights.

That said, the standard panel with the Y-shaped grooves is likely the best option in terms of performance. As Corsair stated, it boosts airflow by up to 12%. But given the nifty look of some of these parts, you might be tempted. Cooling isn’t everything, after all.

The removable motherboard mounting tray inside the case is also customizable. Corsair showed off several prototype trays that could be the start of something special. Assuming they come to market, you could swap the tray for a few skeletal metal options with different aesthetics, or a mostly transparent acrylic one.

If you opt for the Frame 4000D configuration that doesn’t come with fans, you’ll also have a wide range of options for adding your own, thanks to Corsair’s Infinirail mounting system. Infinirail makes several of the fan-mounting locations of this case adjustable and enables you to fit anything from 120mm to 180mm fans on the top panel and between 120mm and 200mm fans on the front.

The case also has a built-in adjustable support for your graphics card, which is helpful for long and heavy models.


Corsair's Not Done Improving the Frame

To complement these existing customization options, Corsair is working on other attachments for this case. One that's already done would go on the lower left side of the system: It's an elongated touch-screen display inside a mounting bezel. Corsair showed off this $249.99 touch panel, called the Xeneon Edge, which looks mighty cool and makes the system really pop.

Another option for this space is a "high airflow" panel that covers this lower third of the left side with a metal plate with Y-shaped cut-throughs, behind which you might mount a bank of fans or a 360mm radiator.

This case was officially released during CES and is now available for purchase, but you may need to wait a bit longer on those customizable accessories. They aren’t popping up yet on Corsair’s digital storefront, and some are officially in the prototype stage only. Watch out for a full review from PCMag later this year.

My Experience

I have been a technology journalist for almost 30 years and have covered just about every kind of computer gear—from the 386SX to 64-core processors—in my long tenure as an editor, a writer, and an advice columnist. For almost a quarter-century, I worked on the seminal, gigantic Computer Shopper magazine (and later, its digital counterpart), aka the phone book for PC buyers, and the nemesis of every postal delivery person. I was Computer Shopper's editor in chief for its final nine years, after which much of its digital content was folded into PCMag.com. I also served, briefly, as the editor in chief of the well-known hard-core tech site Tom's Hardware.

During that time, I've built and torn down enough desktop PCs to equip a city block's worth of internet cafes. Under race conditions, I've built PCs from bare-board to bootup in under 5 minutes. I never met a screwdriver I didn't like.

I was also a copy chief and a fact checker early in my career. (Editing and polishing technical content to make it palatable for consumer audiences is my forte.) I also worked as an editor of scholarly science books, and as an editor of "Dummies"-style computer guidebooks for Brady Books (now, BradyGames). I'm a lifetime New Yorker, a graduate of New York University's journalism program, and a member of Phi Beta Kappa.

The Technology I Use

I use a lot of computers on rotation in my daily work, but I rely on just a few to get things done. I split my work life mostly between a Microsoft Surface Laptop 3 (a 15-inch Ryzen model), paired with a Lenovo ThinkVision portable monitor, and a custom-built big-chassis Windows 10 desktop PC that has served me well for years now. (Specs: Liquid-cooled Intel Core i7-6950X Extreme Edition, 32GB of RAM, and a GeForce GTX 1080 card.) That's all in a giant chassis with six hard drives and SSDs packing its bays. (As I upgrade systems, I just keep moving the old warhorse drives over.) This behemoth is hooked up to a 32-inch LG monitor.

I also have a bunch of PCs around the house, all custom builds: another one attached to my main TV (for gaming and occasional forays into VR), a mini-PC on the bedroom TV (acting as a media server), and a Mini-ITX desktop in a corner of the living room...just because. I carry around an oversize OnePlus phone, but when I do long-haul travel, a vintage iPod Touch comes along, too, for old times' sake.

I wasn't always a PC guy. I cut my teeth on a cassette-drive-equipped Commodore VIC-20 in the 1980s. But I got serious with Apple desktops in the early 1990s, starting with a Macintosh SE, then a Macintosh LC, and finally one of the short-lived Umax "clone" Macs, before building my first PC and never looking back.

With all my typing and editing work over the years, I've become a huge proponent of thumb trackballs, which minimize wrist action (and my wrist pain). I have a secret cache of the long-discontinued Microsoft Trackball Optical Mouse (my personal favorite), held in an undisclosed location.

My Experience

I have been interested in science and technology for as long as I can remember, spurred on by a fondness for video games. I learned to work in Windows and manipulate files to get buggy games to work, and I learned to build and upgrade PCs for better performance.

In my role at PCMag for the past four years, I’ve deeply enjoyed the opportunity to share my knowledge and expertise. Before PCMag, I wrote for Tom's Hardware for three years, where I covered tech news, deals, and wrote some hands-on reviews. After working as a PCMag contributor for a time reviewing desktops, PC cases, budget processors, and motherboards, I now focus on testing and reviewing processors and graphics cards and sharing my insights on the industry.

The Technology I Use

As a PC component reviewer, almost every PC I use is a custom-built system. The only exceptions are my laptops, which I modify and tweak to improve performance, too. My current best laptop is a 16-inch Lenovo Slim 5 with an AMD Ryzen 7 7840HS processor and an Nvidia GeForce RTX 4060. My home-built desktop has an AMD Ryzen 9 9950X processor with an Nvidia GeForce RTX 5080 GPU—all the better to play Kingdom Come Deliverance II with.

My lifelong love of computers and gaming has led me to amass a collection of old tech devices. I have several custom-built PCs, ranging from a Windows 98-based Pentium II to modern hardware, that I use to enjoy older games. These sit alongside my collection of retro game consoles, which includes an NES, a Super Nintendo, a Sega Genesis, an original PlayStation, and a first-generation Xbox.

I'm also a connoisseur of budget tech devices, like my smartphone of choice. Currently, I use a Poco X7 Pro that I bought in 2025 and love so far.
