Compact Workstation Mini PC

The Lenovo ThinkStation Mini pairs a 14th Gen Intel Core i9-14900 processor with an NVIDIA T400 4GB GDDR6 graphics card in a 1.5 inch high chassis. It ships with 16GB DDR5 memory, a 512GB PCIe NVMe SSD and Windows 11 Home pre-installed. The 300W power supply supports the 24-core, 32-thread CPU and dedicated GPU for professional applications.

Step Up From Integrated Graphics

The discrete T400 adds 4GB GDDR6 video memory and native multi-display support via HDMI, DisplayPort and three mini-DisplayPort outputs. This configuration suits CAD, GIS and multi-monitor trading desks where integrated graphics lack the frame buffer or output count. Buyers needing certified drivers for ISV applications gain the NVIDIA professional software stack without a full tower workstation.

Sustained Load In A Small Enclosure

The 300W PSU and compact thermal design keep the i9-14900 at its 2.00GHz base clock during extended renders or simulations, with turbo up to 5.8GHz available for shorter bursts. WiFi 6 and Bluetooth 5.3 maintain connectivity while the RJ-45 port provides wired stability. The system is not for users who need internal drive bays, full-height expansion cards or liquid cooling headroom.
