Workstation for CAD and simulation

This Adamant Custom tower pairs a 24-core Intel Core Ultra 9 285K with an Nvidia RTX PRO 4000 Blackwell graphics card. Thirty-two gigabytes of DDR5 memory and an 8 TB NVMe array feed the GPU for large assemblies. Liquid cooling keeps the CPU stable during extended solves. Windows 11 Pro ships pre-installed.

Step up from entry-level workstations

The 24-core processor and 24 GB GPU memory replace systems that stall on multi-physics studies or high-poly modelling. Faster clock speeds up to 5.70 GHz and 36 MB L3 cache cut iteration time. The jump is worth it when 32 GB RAM and dual 4 TB NVMe drives eliminate swapping on active projects.

Headroom for large datasets

Dual Samsung 990 PRO drives deliver up to 7450 MB/s reads and 6900 MB/s writes for scratch space. A 10 TB HDD with 256 MB cache stores archives and libraries. Four memory slots support up to 192 GB DDR5 when models outgrow the factory 32 GB. Wi-Fi 7 and 2.5 Gbps LAN move files between network stores.

Questions about this item

What case dimensions and motherboard form factor does the Adamant Custom workstation require?

The Antec P20 mid-tower measures 469 mm deep, 220 mm wide and 490 mm high and accepts the ATX Z890 motherboard.

How is the 360 mm liquid cooler installed, and what step is often missed?

Mount the 360 mm radiator to the case top or front using the supplied brackets, then connect the pump header to the CPU_FAN connector on the Z890 board; forgetting that header causes the BIOS to report a fan error.

Which storage drives may need replacement first and what are their capacities?

The two 4 TB Samsung 990 PRO M.2 SSDs and the 10 TB HDD are the primary drives; the SSDs handle the OS and active projects while the HDD stores bulk data.
