Custom-built workstation desktop

This Adamant Custom tower pairs a 24-core Intel Core i9-14900K processor with an Nvidia GeForce RTX 5090 graphics card. The system ships with Windows 11 Pro installed on a 1TB Samsung 990 PRO NVMe drive. A 360mm liquid cooler and a 1200W 80 PLUS Gold power supply support the high-wattage components inside an Antec P20 tempered-glass case.

Ideal for AI development and heavy rendering

The 192GB DDR5 capacity and RTX 5090 32GB GPU suit machine-learning training, 3D modelling and video editing workloads that demand large memory pools. Buyers who need ECC memory error correction or multi-GPU scaling should look at dedicated server platforms instead.

192GB DDR5 maximum memory

The motherboard supports a 192GB ceiling across four slots, and this build already populates that limit. Any future upgrade would require replacing existing modules rather than adding more, so confirm the capacity matches your long-term dataset sizes before purchase.

Questions about this item

Will the 469 mm deep Antec P20 case fit on my desk?

The case measures 469 mm deep, 220 mm wide and 490 mm high, so check your available desk depth before ordering.

How do I install the 360 mm liquid cooler, and what step is often missed?

Mount the radiator to the top or front using the included brackets, connect the pump header to the CPU_FAN socket, then plug the three 120 mm fans into the AIO_FAN or SYS_FAN headers — forgetting the pump power cable is the common error.

Which drive will need replacement first, the 1 TB Samsung 990 PRO or the 10 TB HDD?

The mechanical 10 TB HDD has moving parts and a 256 MB cache, so it typically reaches end of life before the solid-state 1 TB NVMe SSD.
