12-Core Ryzen Workstation for Modelling and AI

This system ships with a 12-core AMD Ryzen 9 9900X3D processor reaching 5.50 GHz and 128 GB of DDR5 memory. It targets professionals running modelling, video editing, rendering and AI learning workloads that demand high core counts and large memory capacity. The 4 TB NVMe SSD provides fast local storage for active projects.

Mid-Tower Build with Liquid Cooling and Front I/O

A 240 mm liquid cooler handles the CPU while the CoolerMaster HAF 500 case supplies front 200 mm ARGB fans and a rear 120 mm ARGB fan. Front panel ports include two USB 3.2 Gen 1 Type-A, one USB 3.2 Gen 2 Type-C and audio jacks. The TUF X870-PLUS motherboard adds rear USB4 40 Gbps Type-C ports, 2.5 Gb Ethernet and Wi-Fi 7 connectivity. Internal bays accept two 3.5-inch and two 2.5-inch drives for future expansion.

Upgrade from Smaller Memory or SATA Storage Systems

Builders moving from 64 GB or lower DDR5 kits gain headroom for larger datasets and simultaneous virtual machines. Replacing a SATA SSD with the 4 TB PCIe 4.0 NVMe drive cuts load times for heavy assets. The 850 W Bronze PSU and AM5 platform support further GPU or storage upgrades. Buyers who need more than 192 GB maximum memory or multiple GPU slots should look elsewhere.
