24-Core Workstation for AI and Rendering

This Adamant Custom desktop pairs a 24-core Intel Core i9-14900K with an Nvidia GeForce RTX 5090 32GB GPU. It targets professionals running AI learning, 3D modelling and heavy rendering workloads alongside high-refresh gaming. The system ships with Windows 11 Pro on a 2TB Samsung 990 PRO NVMe drive and a 10TB HDD for bulk storage.

Pre-Built Liquid Cooling and Component Access

The PC arrives fully assembled with a 360mm quiet-edition AIO cooler already mounted on the LGA 1700 socket. No cooler installation or thermal-paste application is required. The Antec P20 mid-tower uses tempered glass panels secured by thumbscrews, giving tool-less access to the four DDR5 slots, four M.2 connectors and two 3.5-inch drive bays for future upgrades.

Suited for High-VRAM Workloads.

The 64GB DDR5 kit and 32GB GPU frame buffer suit creators who need large texture pools and dataset residency. Buyers who want a smaller chassis, lower power draw or a system without liquid cooling should look elsewhere. The 1200W 80 PLUS Gold PSU and 2.5Gb Ethernet with Wi-Fi 6 and BLUETOOTH 5.2 complete a platform built for sustained heavy compute.

Questions about this item

How do I confirm the liquid cooler is running after I power on the PC?

The 360 mm AIO quiet edition water cooler should spin its 140 mm fan and show coolant flow in the transparent tubing; CPU temperatures under load should stay well below the 6.00 GHz boost ceiling.

What components ship inside the Antec P20 case and what must I add?

The box contains the complete build — i9-14900K on the Z790 TUF board, 64 GB DDR5, 2 TB Samsung 990 PRO NVMe, 10 TB HDD, RTX 5090 32 GB, 1200 W 80 PLUS Gold PSU, Wi-Fi 6 and BLUETOOTH 5.2 — only a monitor, keyboard and mouse are needed separately.

Which memory configuration should I choose if I want room to reach the 192 GB maximum later?

The system arrives with 64 GB DDR5 installed across four slots; to leave space for future expansion, select the 64 GB option now and add matching DDR5 modules in the remaining slots when required.
