24-Core Liquid-Cooled Workstation

This business desktop pairs a 24-core Intel Core i9-14900K with a 360mm liquid cooler in a mid-tower chassis. It ships with 32GB of DDR5 memory, a 4TB NVMe SSD, a 10TB hard drive and an Nvidia RTX A400 graphics card. Windows 11 Pro is pre-installed and the system is described as AI ready.

Suited for Multi-Threaded Professional Loads

The 24 cores and 32 threads handle rendering, simulation and heavy multitasking, while the four Mini DisplayPort outputs drive multiple professional displays. Buyers who need more than 32GB of memory out of the box or who require certified drivers for a broader range of ISV applications should evaluate alternative configurations.

Bundled Storage and Connectivity Extras

The 4TB NVMe drive provides fast boot and project access, and the 10TB hard drive adds high-capacity local storage for archives. The motherboard includes Wi-Fi 6, 2.5Gb Ethernet, multiple USB 3.2 and USB 2.0 ports plus front-panel USB-C, so peripherals and network links connect without extra adapters.
