Business Mini Desktop

This refurbished HP 800 G9-MINI is a compact business desktop built around an Intel Core i5-12500T processor. It ships with 16GB DDR4 memory and a 512GB NVMe drive, plus Windows 11 Pro 64-bit pre-installed. The small 1.35" x 6.89" x 6.97" chassis fits tight workspaces while providing essential connectivity for office tasks.

6-Core 12th Gen Processor

The single specification that defines suitability is the Intel Core i5-12500T, a 6-core 64-bit CPU with 18MB L3 cache and 7.5MB L2 cache running at 2.0GHz base frequency. This 12th Gen part delivers mainstream multi-threaded performance for typical business workloads. Buyers needing higher core counts or unlocked multipliers for sustained heavy compute should look elsewhere.

16GB DDR4 and 512GB NVMe

The 16GB DDR4 memory handles standard multitasking across office suites, browser tabs and video calls without pressure. The 512GB NVMe SSD provides fast boot and application launch for the OS and active project files. Users working with large local datasets, virtual machines or extensive media libraries will find the capacity limiting and should plan for external storage.

Questions about this item

What does the i5-12500T's 2.0 GHz base clock deliver in daily office work?

The 6-core processor runs at 2.0 GHz base with 18 MB L3 cache, handling typical business multitasking and productivity applications without needing active cooling in the mini chassis.

How do the USB 3.2 Gen 2x2 Type-C and DisplayPort 1.4 ports limit external display and data speeds?

The front USB 3.2 Gen 2x2 Type-C supports up to 20 Gbps data, while two DisplayPort 1.4 and one HDMI output drive up to three monitors from the integrated graphics.

Will the 1.35-inch high mini case fit behind a monitor mount or in a 1U shelf?

The chassis measures 1.35" x 6.89" x 6.97" and weighs 3 lbs, so it fits standard VESA mounts and shallow rack shelves with room for cable clearance.
