Built for professional workloads

This business desktop pairs a 14‑Core Intel Core Ultra 5 245K processor with 64GB of DDR5 memory and an Nvidia RTX A400 graphics card. The combination targets workstation users who need reliable multi‑threaded compute and professional GPU drivers for CAD, media encoding or AI‑assisted applications. Windows 11 Pro 64‑bit is pre‑installed and the system is described as AI Ready.

Liquid‑cooled chassis with versatile I/O

A 240mm liquid cooler keeps the CPU at stable temperatures while the Antec P20 mid‑tower case supplies three 120mm front fans and dust filters on every intake. Front‑panel connectivity includes two USB 3.0 ports, one USB 3.2 Gen 2 Type‑C port and audio jacks. The rear I/O adds Thunderbolt 4, USB 20Gbps and 10Gbps Type‑C ports, multiple USB 5Gbps and 2.0 ports, plus 2.5G Ethernet, Wi‑Fi 7 and Bluetooth 5.4.

Upgrades from entry‑level workstations

The 2TB Samsung 990 PRO NVMe drive and 10TB hard drive replace smaller SSD‑only configurations, giving both fast boot and deep archival capacity. Builders who need more than 64GB of RAM can expand to 192GB, while the four Mini DisplayPort outputs support multi‑monitor setups that integrated graphics cannot drive. Buyers who require multiple high‑end GPUs or ECC memory should look elsewhere.
