Compact workstation for professional workloads
The Lenovo ThinkStation Mini packs a 14th Gen Intel i9-14900 processor with 24 cores and 32 threads into a 7 by 7.25 by 1.5 inch chassis. It targets engineers, analysts and creators who need multi-threaded compute power in a space-constrained office or lab environment. The 300W power supply drives the CPU and a dedicated NVIDIA T400 graphics card with 4GB GDDR6 memory.
Step up from integrated-graphics mini PCs
This configuration replaces systems that rely solely on integrated graphics for visualisation or light GPU-accelerated tasks. The jump is worth it when workflows use CAD viewports, multi-display setups across the HDMI, DisplayPort and three mini-DisplayPort outputs, or compute workloads that benefit from dedicated GDDR6 video memory. The 8GB DDR5 SO-DIMM provides a baseline for single-channel operation.
8TB NVMe headroom for active projects
The single 8TB PCIe NVMe SSD holds operating system, applications and large project datasets without secondary drives. It comfortably handles current working sets, local caches and scratch files for video or simulation work. Capacity runs out when archival libraries, raw footage repositories or multi-terabyte databases must stay online simultaneously, requiring external or network storage expansion.

Questions about this item
What are the exact dimensions of the Lenovo ThinkStation Mini so I can check if it fits my desk space?
The unit measures 7 inches wide by 7.25 inches deep by 1.5 inches high and weighs 3.1 pounds, making it compact enough for tight desk areas or VESA mounting behind a monitor.
How do I install additional memory in this Mini PC and what slot type does it use?
Open the chassis, locate the SO-DIMM slot, and insert a DDR5 module at an angle until it clicks; the system ships with one 8GB stick installed, so a second module adds dual-channel performance.
When will the 300W power supply need replacement under typical workloads?
The internal 300W PSU is rated for continuous operation; plan to evaluate it after several years of heavy use or if the system becomes unstable under sustained 24-core CPU and T400 GPU loads.
