Workstation for CAD and AI

This business desktop is built around a 14-core Intel Core Ultra 5 245K processor and an Nvidia RTX PRO 4000 Blackwell graphics card with 24GB of video memory. It targets engineers and designers who need certified drivers for SolidWorks modelling and local AI inference workloads. The system ships with Windows 11 Pro 64-bit and liquid CPU cooling for sustained performance.

64GB DDR5 memory at 192GB ceiling

The motherboard supports a maximum of 192GB across its DDR5 slots, so the installed 64GB kit leaves three quarters of the capacity open for future expansion. Buyers who need more than 192GB of system memory cannot meet that requirement with this platform. The four M.2 connectors and four SATA 6Gb/s ports provide additional storage lanes beyond the factory drives.

Z890 ATX build in a 4000D case

The TUF Z890-PLUS WiFi7 motherboard fits the Corsair 4000D tempered-glass chassis, which offers two 3.5-inch and two 2.5-inch internal bays for extra drives. Rear I/O includes Thunderbolt 4, USB 20Gbps and 10Gbps Type-C ports, plus 2.5G Ethernet, Wi-Fi 7 and Bluetooth 5.4. An 850W 80 PLUS Bronze power supply with a 140mm fan powers the complete assembly.

Questions about this item

What does the 4.2 GHz base clock on the Intel Core Ultra 5 245K mean for daily workloads?

The 14-core CPU runs at 4.2 GHz base and can boost to 5.20 GHz across its 20 threads, giving strong single-thread speed for CAD modelling and responsive multitasking in Windows 11 Pro.

How does the PCI Express x16 link affect the RTX PRO 4000 Blackwell 24GB in this build?

The GPU connects through a full x16 slot on the Z890-PLUS TUF motherboard, so the 24 GB card receives maximum bandwidth for AI workloads and professional graphics.

Will the Corsair 4000D case and 240 mm liquid cooler fit together without clearance issues?

Yes — the 240 mm AIO is mounted in the 4000D's supported radiator positions, and the case dimensions of 490 x 239 x 486 mm provide ample room for the cooler and the RTX PRO 4000 Blackwell.
