Overview

MSI XpertStation WS300 is a deskside AI supercomputer built on the NVIDIA DGX Station architecture and powered by the NVIDIA GB300 Grace Blackwell Ultra Desktop Superchip. With up to 748 GB of coherent memory and dual 400GbE networking through the ConnectX-8 SuperNIC, it is designed to run demanding agentic and multi-model AI workloads locally rather than against a metered cloud endpoint. Two units can be clustered directly for scale-out, and PCIe Gen5/Gen6 NVMe storage sustains multi-model serving.

MSI is shipping the XpertStation WS300 through ASI, D&H and Newegg as of 27 August 2026. The system supports the NVIDIA NemoClaw security layer with the OpenShell runtime for policy-controlled autonomous AI agents, and runs Nemotron 3.5 Lightning — a 30B-parameter mixture-of-experts model with 3B active parameters and context windows up to one million tokens — alongside NVIDIA NeMo Switchyard, an open-source routing library that sends each workflow step to the best-suited model without manual configuration.

Alongside it, MSI EdgeXpert extends the same software story to a compact, always-on appliance based on the NVIDIA DGX Spark platform. Powered by the GB10 Grace Blackwell Superchip with up to 1 petaFLOP of AI compute and 128 GB of coherent unified memory, it runs models up to 200 billion parameters continuously on-device, and clusters up to four units over ConnectX-7. Both platforms target the same shift: enterprises keeping inference on premises to cut recurring cloud cost and retain control of proprietary models and data.
