Compact Workstation
The Lenovo ThinkStation Mini is a 7 × 7.25 × 1.5 in desktop powered by a 14th Gen Intel i9-14900 processor with 24 cores, 32 threads and a 5.8 GHz max turbo. It ships with 16 GB DDR5 SO-DIMM memory, a 256 GB PCIe NVMe SSD and an NVIDIA T400 4 GB GDDR6 graphics card. Windows 11 Pro is pre-installed.
Suited for Professional Workloads
This system suits engineers, analysts and creators who need high single-thread speed and certified professional graphics in a tiny footprint. The 300 W power supply and mini chassis limit future GPU upgrades, so buyers who want more graphics memory or a larger card should look elsewhere. WiFi 6, Bluetooth 5.3 and RJ-45 cover modern connectivity needs.
Memory and Storage Headroom
Sixteen gigabytes of DDR5 handles typical CAD, simulation and multi-app workflows comfortably; heavy datasets or large virtual-machine fleets will push against that ceiling. The 256 GB NVMe drive holds the OS and active projects, but video editors or 3D artists will need external storage for source footage and asset libraries.

Questions about this item
What display cables do I need to use the HDMI, DisplayPort and three mini-DisplayPort outputs on this ThinkStation?
You need an HDMI cable for the HDMI port, a standard DisplayPort cable for the single DP connector and three mini-DisplayPort cables for the mDP ports; all four digital video outputs are driven by the NVIDIA T400 4GB GDDR6 graphics card.
Will my existing USB keyboard and mouse work with the USB 3.2 Type-C port on the front of this mini PC?
The included USB keyboard and mouse connect to the standard USB-A ports; the USB 3.2 Type-C port accepts USB-C peripherals or adapters, so legacy USB-A devices require a Type-C to Type-A adapter or hub.
How can I confirm the NVIDIA T400 4GB GDDR6 GPU is active after I install the latest driver?
Open Windows Device Manager, expand Display adapters and verify NVIDIA T400 appears; then launch NVIDIA Control Panel to see the 4 GB GDDR6 memory listed and run a GPU-accelerated task to observe utilisation.
