12-Core Liquid-Cooled Workstation

This Adamant Custom desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 64GB of DDR5 memory and a 2TB NVMe SSD. A 240mm liquid cooler manages CPU thermals while the GeForce RTX 5070 graphics card handles visual workloads. Windows 11 Pro is pre-installed on the system.

Suited to heavy multitasking and GPU compute

The 12-core CPU and 64GB memory capacity serve professionals running virtual machines, rendering pipelines or large datasets. The single RTX 5070 with 12GB VRAM limits buyers who need multi-GPU scaling or higher video memory for 8K workloads. Builders requiring more than two 3.5-inch drive bays should consider a larger chassis.

Sustained load behaviour

The 240mm AIO cooler and 850W Bronze-rated power supply are designed to maintain stable operation during extended rendering or compile sessions. The Corsair 4000D case provides airflow paths for the liquid radiator and GPU. Thermal throttling is mitigated by the cooler's 140mm fan and the motherboard's VRM heatsinks.

Questions about this item

Does this system ship with a monitor, keyboard, and mouse so it works out of the box?

No peripherals are included. You must supply your own display, keyboard, and mouse; the rear panel provides 2 USB4 Type-C, 1 USB 10 Gbps, 3 USB 5 Gbps, and 4 USB 2.0 ports for them.

Will my existing SATA SSDs or hard drives install inside the Corsair 4000D case?

Yes. The case has two 3.5-inch and two 2.5-inch internal bays, and the PRIME X870-P motherboard offers two SATA 6 Gb/s connectors for those drives.

How can I verify the liquid cooler is running after I power on the PC?

The 240 mm AIO uses a 140 mm fan; listen for its low-noise spin and check CPU temperatures in Windows 11 Pro — they should stay well below the 5.50 GHz boost ceiling under load.
