An eight-core Ryzen 7 9700X workstation with an RTX PRO 5000 48GB GPU, 128GB DDR5, 4TB NVMe and 10TB HDD for SolidWorks modelling and AI learning
The Adamant Custom desktop pairs an 8-core AMD Ryzen 7 9700X processor with an Nvidia RTX PRO 5000 Blackwell graphics card holding 48GB of video memory. A 240mm liquid cooler manages thermals inside an Antec P20 mid-tower case finished in black. Windows 11 Pro is installed and the system is described as AI Ready for professional workloads.
This configuration targets engineers running SolidWorks or similar CAD packages and developers training local AI models who need a single high-capacity GPU. The motherboard provides four memory slots populated with 128GB DDR5 and four M.2 connectors, yet the case only fits two 3.5-inch drives internally. Buyers who want more storage bays or a second full-length graphics card should look at a larger chassis.
The RTX PRO 5000 Blackwell ships with 48GB of onboard memory, which is the single specification that determines whether the workstation can hold large datasets or complex scenes entirely in video RAM. If your workflow exceeds that capacity you will need a different graphics solution; if it fits, the 128GB system memory and 4TB NVMe SSD provide fast supporting storage.

The 8-core processor can boost up to 5.50 GHz under load, and the 240 mm liquid cooler keeps temperatures low enough to sustain those speeds during long rendering or simulation sessions.
The card runs at full PCIe 4.0 x16 bandwidth, so the 48 GB of GPU memory feeds compute workloads without a bottlenecked bus.
Yes — the case supports E-ATX boards, has room for a 240 mm radiator up top, and its 469 mm depth clears the graphics card with space for front intake fans.
