Mini Workstation for Professional Tasks
The Lenovo ThinkStation Mini Desktop pairs a 14th Gen Intel Core i9-14900 processor with an NVIDIA T400 4GB GDDR6 graphics card. It delivers 24 cores and 32 threads for demanding workflows such as CAD, data analysis and multi-application productivity. The system ships with Windows 11 Home pre-installed and includes a USB keyboard and mouse for immediate deployment.
Compact Chassis with Versatile Display Outputs
A 300W power supply fits inside a 7 by 7.25 by 1.5 inch black case weighing 3.1 lb, allowing placement on a desk or behind a monitor. Video connectivity covers HDMI, one full-size DisplayPort and three mini DisplayPort connectors, supporting up to four displays without adapters. Wired networking uses an RJ-45 port while WiFi 6 and Bluetooth 5.3 handle wireless peripherals. A USB 3.2 Type-C port and a headphone/microphone combo jack sit on the front for quick access.
Efficient Cooling Within a 300W Envelope
The 300W power supply limits total system draw, so the cooling solution is sized for sustained loads typical of professional applications rather than continuous maximum turbo. Under normal office workloads the fan profile remains quiet enough for open-plan environments. The small internal volume restricts airflow, making this platform unsuitable for buyers who need extended all-core turbo or multiple high-power add-in cards.

Questions about this item
Does the PCI Express x16 interface limit the NVIDIA T400 4GB GDDR6 graphics card to x8 electrical speed?
The T400 connects through a PCI Express x16 slot and uses the full x16 electrical link, so the GPU is not capped to x8 bandwidth.
What are the exact dimensions and weight to confirm the mini PC fits my VESA mount?
The chassis measures 7 in x 7.25 in x 1.5 in and weighs 3.1 lb, so verify your VESA bracket supports that footprint and weight.
How do I install additional DDR5 SO-DIMM modules and which slot-population mistake should I avoid?
Remove the bottom cover, insert the SO-DIMM at an angle until the clips snap, and do not leave the primary slot empty while populating only the secondary slot.
