Core Specification

This desktop is a liquid-cooled tower workstation built around a 24-core Intel Core i9-14900K processor and a Z790 TUF motherboard. It targets professionals and enthusiasts who need high multi-threaded throughput for rendering, compilation or simulation workloads. The system ships with Windows 11 Pro and 128GB of DDR5 memory. Buyers requiring a discrete graphics card for GPU-accelerated tasks or high-refresh gaming will need to add one separately.

Thermals and Power

A 360mm quiet-edition AIO cooler handles the CPU heat load while three 120mm front fans and a 140mm PSU fan move air through the Antec P20 chassis. Dust filters on the bottom, front and top panels help maintain airflow over time. The Thermaltake Smart 850W 80 PLUS Bronze unit delivers power with over-voltage, under-voltage, over-power and short-circuit protection. Acoustic output stays low during typical workloads thanks to the liquid loop and low-noise fan profiles.

Build and Connectivity

The tempered-glass mid-tower measures 469 x 220 x 490 mm and offers two 3.5-inch or 2.5-inch internal bays plus two dedicated 2.5-inch bays. Rear I/O includes two USB Type-C, two USB 3.2 Gen 2 and four USB 3.2 Gen 1 ports; internal headers add a further USB 3.2 Gen 2 Type-C, USB 3.2 Gen 1 and two USB 2.0 connections. Storage uses four SATA 6Gb/s ports and four M.2 slots, currently populated with a 1TB Samsung 990 PRO and a 10TB HDD. Networking relies on Intel 2.5Gb Ethernet, Wi-Fi 6 and Bluetooth 5.2.

Questions about this item

How do I install the 360 mm Quiet Edition AIO liquid cooler in the Antec P20 case?

Mount the radiator to the top panel using the included brackets and screws, orient the tubes toward the rear, and connect the pump header to the CPU_FAN connector on the Z790 TUF motherboard.

What maintenance will the 360 mm AIO and 10 TB HDD need later?

The AIO is a sealed unit requiring no coolant service; dust the radiator fins and three 120 mm front fans every 6–12 months, and run SMART checks on the 10 TB drive annually.

What limit appears first during sustained all-core loads on the i9-14900K?

The 24-core CPU will reach its thermal throttle point before the 360 mm AIO can dissipate the full package power, so clock speeds drop to stay within safe temperatures.
