Purpose-built workstation

This system is assembled for professionals running SolidWorks, CAD, CAM and CAE modelling workloads. The 24-core Intel Core i9-14900K and 128GB DDR5 give headroom for large assemblies and simulation tasks. An Nvidia RTX PRO 4500 Blackwell with 32GB VRAM drives certified drivers for ISV applications. Windows 11 Pro 64-bit is pre-installed and ready for domain integration.

Build and connectivity

A Corsair 4000D tempered-glass chassis houses a 360mm liquid cooler and an 850W 80 PLUS Bronze supply with Japanese main capacitors. The Z790 TUF motherboard adds Wi-Fi 6 and BLUETOOTH 5.2 alongside rear I/O that includes two USB Type-C ports, two USB 3.2 Gen 2 and four USB 3.2 Gen 1. Internal bays provide two 3.5-inch and two 2.5-inch positions for the included 10TB HDD and future expansion.

Interface limits

The 4TB Samsung 990 PRO operates over PCIe 4.0x4, so sequential throughput tops out at the drive's rated 7450 MB/s read and 6900 MB/s write. Four M.2 connectors share chipset lanes with the four SATA 6Gb/s ports, meaning populating every slot can reduce bandwidth for additional NVMe drives. The 2.5Gb Ethernet link caps wired network transfers at that rate.

Questions about this item

What PCIe generation does the M.2 slot for the Samsung 990 PRO SSD use, and what read speed does that cap in practice?

The M.2 slot runs PCIe 4.0 x4, so the 4 TB Samsung 990 PRO tops out at its rated 7 450 MB/s sequential read.

What case dimensions and drive bays must the chassis accommodate for this mid-tower build?

The Corsair 4000D measures 490 x 239 x 486 mm and provides two 3.5-inch and two 2.5-inch internal bays for the 10 TB HDD and any extra SSDs.

How is the 360 mm liquid cooler mounted, and which orientation step do builders often miss?

The 360 mm AIO radiator fits the top or front of the 4000D; the step many miss is installing the fans as intake so coolant flows through the radiator before exhausting out the case.
