Workstation for CAD and AI

This business desktop pairs a 20-core Intel Core Ultra 7 265K with an Nvidia RTX PRO 4000 Blackwell GPU and 128GB of DDR5 memory. It targets engineers and designers who need certified drivers for SolidWorks and local AI inference. The system ships with Windows 11 Pro 64-bit and a 2TB NVMe boot drive plus a 10TB hard drive for project archives.

Installation notes

The Antec P20 mid-tower arrives fully assembled with a 240mm liquid cooler and a Thermaltake Smart 850W power supply already installed. Front-panel ports include two USB 3.0, one USB 3.2 Gen 2 Type-C and audio jacks. Builders should verify that the 469mm case depth fits their desk space and that the 2.5G Ethernet cable reaches the network switch.

Pre-order checks

Confirm your monitor has a compatible input for the RTX PRO 4000 Blackwell, as no display is included. The Z890 motherboard provides four M.2 slots and four SATA ports, so plan any additional storage around those limits. Maximum memory supported is 192GB, leaving headroom beyond the factory 128GB DDR5. Wi-Fi 7 and Bluetooth 5.4 are onboard for wireless connectivity.

Questions about this item

How can I confirm the liquid cooler is keeping the 20-core CPU at safe temperatures after assembly?

The 240 mm AIO liquid cooler is designed for the 20-core Intel Core Ultra 7 265K; monitor CPU temperatures in Windows 11 Pro or BIOS to verify they stay within normal limits under load.

What components are included and what must I purchase separately to start working?

The system ships with the Antec P20 case, Z890 motherboard, 128 GB DDR5, 2 TB Samsung 990 PRO NVMe SSD, 10 TB HDD, RTX PRO 4000 Blackwell 24 GB GPU, 850 W PSU, Windows 11 Pro, Wi-Fi 7 and Bluetooth 5.4; a monitor is not included.

Which memory capacity should I choose if I need room for future expansion beyond the installed 128 GB?

The motherboard supports up to 192 GB of DDR5, so the current 128 GB leaves 64 GB of headroom for adding more modules later.
