FRAME 4000D Build Log by Zafiast

We sent over the FRAME 4000D to Zafiast so they could do a test build and provide some feedback. From this point, the rest of the page is in their own words. Let's take a look.

CORSAIR announced the new FRAME 4000D at CES 2025. I was given an early sample to build in. This is a quick overview, and I hope it helps those of you who already have the case and are wondering what to do with it or who are contemplating whether to buy it.

Compared to the previous 4000D RGB AIRFLOW, this new 4000D version is slightly larger at 487 x 486 x 239 mm, compared to 466 x 453 x 230. This case is closer to the 5000D RGB AIRFLOW in terms of capacity rather than the 4000D, with the same 12 fan mounting positions as the 5000D. What is different, however, is the presence of the new InfiniRail system (first seen on the 9000D). This system allows you to mount fans of various sizes (120 to 200 mm on the front, and 120/140/160 mm on the top) without CORSAIR having to include a fixed rail for each particular size.

In this build, I am using 9 RX MAX fans on the front, top, and bottom positions and 3 RX fans on the side position, along with a side-mounted tube down the radiator. Yes, a top mount exists, but I am a firm believer that mounting the radiator on the side will get you the best performance.

• CPU: Intel i5-14600K
• Motherboard: MSI Z790 Tomahawk MAX WiFI
• GPU: MSI Ventus 3x 4070 Super
• PSU: CORSAIR RM850x SHIFT
• Storage: 2x 1TB WD SN850X
• Memory: CORSAIR Dominator Titanium 2x16GB DDR5-7200 + Lighting Enhancement Kit
• Case: FRAME 4000D
• CPU Cooler: CORSAIR iCUE LINK TITAN 360 RX LCD
• Fans: 9x CORSAIR iCUE LINK RX120 MAX
• Accessories: LS430 AURORA / ARGB PSU Strips / LC100 Starter Kit

Side view: Notice the airflow side panel, cutouts for back connect motherboards, the integrated GPU support and the LINK HUB cutout in the motherboard backplate.

Front view with and without the cover: I/O ports are now on the bottom – great if you use the PC on a desk, not so good if it’s on the floor. InfiniRail lets you mount any size of fan on the front from 120 to 200mm.

Top view with and without the cover: Only one of the rails in adjustable on the top, so 120mm fans will look offset. Fits 120/140/160mm fans.

Rear view: It fits 120 or 140 mm on the rear. The top, side glass, side airflow, other side panel, PCIe slots, and PSU have thumbscrews. For vertical GPU mounting, the entire PCIe slot assembly comes out as a single piece.

After removing the assembly, turn it 90 degrees, align the hooks with the notches in the case, and then tighten the thumbscrews. You will need to supply your own riser cable, and vertical mounting means you can’t mount the two fans on top of the PSU (same with the 3500X).

The accessory kit contains a fan bracket for the side fans, screws/standoffs, a replacement GPU support holder (pictured for when side fans are installed), and plastic covers for the side airflow panel and back connect holes.

The cable cover was removed; you can see how empty the bottom of the case is. You can also spot the additional plate on the bottom for another LINK HUB and drives. Take note of the 2 sets of mounting holes for the side fan bracket and cable bar (below the front panel cables on the bottom).

First, I installed the motherboard, then proceeded to install the radiator, pump, and front/side/rear fans. The pump cable is running along the tubes. The side fan bracket (and cable bar) can be mounted closer to the motherboard or closer to the front fans via the two sets of mounting holes. You must set it to the front fan position when using side fans to make space for cabling; it is in the wrong position in the picture above.

I originally wanted to use RX MAX fans on the side radiator but realized that they would not fit—the GPU cannot be inserted fully (look at the PCIe slot). This will also be an issue for those using thicker rads, such as those found on the ARCTIC Liquid Freezer III. In this situation, you must either vertically mount the GPU or top mount the radiator.

The build is complete. When the side bracket is in the correct position, notice the gap in the case that has opened up for the 24-pin ATX power.

Things I like:

• Integrated GPU support
• Rotatable PCIE expansion slots
• Thumbscrews everywhere
• Cutout for LINK hubs
• Airflow side panel
• Lots of space for cabling, especially on the bottom
• Lots of cable management aids
• It fits twice the fans as compared to the old 4000D
• In general, very easy to build in

Things I don’t:

• No side-mounted rad + thick fan combo (thick rads don’t work too; Liquid Freezers beware)
• The front panel has a weird mesh design (to me)
• Front rails are not intuitive to secure; attempting to lock the rails by tightening the screws can lead to stuck screws. You aren’t meant to tighten them too much; use the clips to mount the fans to avoid this.
• At first glance, it is not clear what the clips in the accessory kit are for. They are actually meant to mount the front fans. I ended up skipping those and mounting the fans directly on the rail instead.
• Glass takes some force to come off; it can be scary. Don’t take it off on a tile floor.
• No PCIe riser cable is included.

In conclusion, it is a fantastic case to get if you’re new to PC building. This case includes all the “modern” improvements you would expect to find in cases, such as thumbscrews in almost every screw position, rotatable PCIe slots, and cable management aids. Innovations in this case that you would not find in most other cases include integrated GPU support, the airflow side panel, and InfiniRail. The case is not without its issues; however, I suggest a thorough read of the manual before beginning your build. Including a PCIe riser would have been nice.
