Liquid-cooled Ryzen 9 9900X3D workstation

This desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 128GB of DDR5 memory and an Nvidia GeForce RTX 5070 graphics card. It targets creators and engineers who need strong multi-threaded compute plus GPU acceleration in a single mid-tower system. Windows 11 Pro is pre-installed and the platform is described as AI-ready. The 240mm liquid cooler keeps the CPU quiet under sustained loads.

240mm AIO and pre-built assembly

The machine arrives fully assembled so there is no component installation required. The Cooler Master HAF 500 case uses standard ATX layout with front 200mm ARGB fans, a rear 120mm ARGB fan and a dedicated 120mm GPU fan for airflow. Front-panel I/O includes two USB 3.2 Gen 1 ports, one USB 3.2 Gen 2 Type-C port, audio jacks and an ARGB control button. Internal drive bays provide two 3.5-inch and two 2.5-inch slots for future expansion.

4TB NVMe plus 10TB HDD storage

A Samsung 990 PRO 4TB NVMe drive delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s for active projects and operating system. A 10TB hard drive with 256MB cache adds deep bulk storage for archives and media libraries. The motherboard offers four M.2 connectors and two SATA 6Gb/s ports so additional drives can be added later. The 850W 80 PLUS Bronze power supply with Japanese main capacitors powers the current configuration with headroom for moderate upgrades.

Questions about this item

How do I verify the 12-core Ryzen 9 9900X3D is running at up to 5.50 GHz after setup?

Open Task Manager or BIOS to confirm the CPU shows 12 cores, 24 threads and a maximum boost clock of 5.50 GHz under load.

The system ships complete with the X870 motherboard, 128GB DDR5, 4TB Samsung 990 PRO SSD, 10TB HDD, RTX 5070 12GB GPU, 240mm liquid cooler, 850W PSU and Windows 11 Pro; no extra parts are required.

Which SSD capacity should I choose between the 4TB NVMe and 10TB HDD?

Use the 4TB Samsung 990 PRO for OS, apps and active projects — it reads up to 7450 MB/s and writes up to 6900 MB/s — and keep bulk media on the 10TB HDD.
