Corsair continues to use its unique chassis that remains specific to the One series of systems. The front has the power button positioned near the top and centered with the headphone/microphone jack, two USB 3.0 ports, and an HDMI port at the bottom. Taking a look at the left side, Corsair has stuck with a similar triangular vented panel design for improved cooling; it is also slightly different from what was seen on the One i160.
Checking out the back, we can see the motherboard has enough I/O to be useful, although still fairly limited compared to more prototypical motherboards one can buy separately. As for the I/O itself you get 1x Set HD Audio ports, 1x Optical S/PDIF out, 2x USB 3.1 Gen 2 Type-A ports, 1x USB 3.2 Gen 2 Type-A port, 1x Thunderbolt port, 2x USB 2.0 ports, 1x PS/2 Keyboard/ mouse combo port, 1x Clear CMOS button, 2x Wi-Fi antenna ports, and 1x RJ45 Ethernet port. Surprisingly, there is no HDMI or other similar port for any sort of usage of the Intel IGP. Just for troubleshooting purposes, I would have liked the ability to utilize the onboard IGP along with a couple more USB ports, just to be safe. Keep in mind that if you have a plethora of USB devices, you may run out of ports and likely need a hub instead since more ports can't be added via a simple add-in card.
Meanwhile, at the bottom, users will find the Corsair SF750 80 Plus Gold power supply and three DisplayPort outputs. After all this time, I still find it odd that they chose to put the HDMI port on the front of the system. Considering there are three DisplayPort outputs, I would think it would make more sense to move one of those to the front and keep the HDMI at the rear for cleaner cabling in a living-room setting.
Finally, the side panel here, much like the other, has a large vented surface through which air is pulled via the 140 mm fan placed at the top of the system. This convection-assisted cooling setup performed quite well previously; however, it will be interesting to see how it handles the more power-hungry Intel Core i9-10900K.
Obviously, thanks to Corsair's iCUE software, you can change the RGB LEDs to any color you wish, with multiple modes available as well. Shown here are just a few of the possible color options.
