Compact workstation for professional workflows
The Lenovo ThinkStation Mini PC pairs a 14th Gen Intel Core i9-14900 processor with 24 cores and 32 threads with an NVIDIA T400 4GB GDDR6 graphics card. Sixteen gigabytes of DDR5 memory and a 1TB PCIe NVMe SSD provide a responsive platform for CAD, content creation and multi-monitor productivity. Windows 11 Pro is pre-installed for immediate deployment in business environments.
Mini chassis with extensive display connectivity
The 7 by 7.25 by 1.5 inch black enclosure houses a 300W power supply and weighs 3.1lb, allowing discreet placement on a desk or behind a monitor. Video outputs include one HDMI, one full-size DisplayPort and three mini-DisplayPort connectors, supporting up to four external displays without adapters. A USB 3.2 Type-C port, RJ-45 Ethernet, WiFi 6 and Bluetooth 5.3 cover modern peripheral and network needs.
Efficient cooling within a low-power envelope
The 300W power supply limits total system draw, so the CPU and discrete GPU operate within a tight thermal budget that keeps fan noise low during typical office and design workloads. Sustained all-core Turbo frequencies up to 5.8GHz are achievable for short bursts before thermal throttling engages. The compact internal layout leaves no room for additional storage drives or full-size expansion cards.

Questions about this item
What PCI Express generation does the NVIDIA T400 use, and what bandwidth does that cap at?
The T400 runs on a PCI Express x16 slot; the exact generation is not in the spec, so the practical ceiling depends on the platform rather than the card alone.
What are the exact dimensions and weight for mounting this Mini PC?
The chassis measures 7 in wide by 7.25 in deep by 1.5 in high and weighs 3.1 lb, so a VESA bracket or shelf must support that footprint and mass.
How is the 16 GB DDR5 SO-DIMM installed, and what step is often missed?
Open the case, align the notch on the SO-DIMM with the slot key, press firmly until the side clips click, then verify in BIOS that both channels show 8 GB each — the click is the step people skip.
