Liquid-cooled workstation desktop with 14-core Intel Core Ultra 5 245K, 128GB DDR5, 8TB NVMe SSD and 10TB HDD
This desktop PC is built around a 14-core Intel Core Ultra 5 245K processor running at 4.2 GHz with a peak of 5.20 GHz. It targets professionals who need strong multi-threaded performance for content creation, data analysis or software development without a discrete graphics card. The 240 mm liquid cooler keeps the CPU stable under sustained loads. Integrated graphics handle display output through HDMI and DisplayPort.
The system ships with 128 GB of DDR5 memory across four slots, leaving room to expand up to 192 GB. Two 4 TB Samsung 990 PRO NVMe drives deliver sequential reads up to 7450 MB/s and writes up to 6900 MB/s for fast project loading. A 10 TB hard drive with 256 MB cache adds deep bulk storage for archives and media libraries. Together they provide 18 TB of total capacity.
The TUF GAMING Z890-PLUS motherboard supplies an LGA 1851 socket, four M.2 connectors and four SATA 6 Gb/s ports for future drive additions. Rear I/O includes Thunderbolt 4, USB 20 Gbps Type-C, three USB 10 Gbps and three USB 5 Gbps ports. Front panel adds USB 3.2 Gen 2 Type-C and two USB 3.0 ports. Intel 2.5 Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4 handle networking. A 750 W 80 PLUS Bronze PSU powers the build.

Check that the pump and both 140mm radiator fans spin up, then monitor CPU temperatures in the BIOS or Windows to confirm they stay low under load.
The drives are pre-installed with all necessary data and power cables connected. No extra cables are required for the storage devices themselves.
