HP Elite Mini 800 G9 — 12-Core 12th-Gen Business Mini PC

A professionally refurbished 1-litre Mini PC built around a 12-core 12th-Gen Intel Core i7-12700T, 16GB of memory and a 512GB NVMe SSD, running Windows 11 Pro. Tested and graded in Melbourne and backed by a 12-month Reboot IT warranty.

Key benefits

• 12 cores in a one-litre chassis. The i7-12700T pairs 8 performance cores with 4 efficient ones, so background work stays off the cores doing your actual job.
• Hides behind the monitor. At roughly a litre in volume the Elite Mini sits under a desk or on a VESA mount, freeing the desk entirely.
• 16GB of memory. Enough headroom to keep a browser full of tabs, Office, Teams and a line-of-business app open together without paging.
• 512GB NVMe SSD. Near-instant boot and file access, with room for a working set of documents and projects rather than just the OS.
• Windows 11 Pro, pre-installed. Domain join, BitLocker and Group Policy are available out of the box for managed fleets.
• Quiet by design. The T-series processor runs at a 35W base power envelope, so the cooling stays unobtrusive in a meeting room or a shared office.

Performance in use

The Core i7-12700T is a 12th-generation hybrid part: eight performance cores handle the work you are waiting on, while four efficient cores absorb the background load — sync clients, antivirus scans, update services. In practice that means a spreadsheet recalculates or a large PDF opens without the pause you get on an older quad-core machine that has to interrupt itself.

With 16GB of memory this is a comfortable machine for a real desktop workload: a dozen browser tabs, Outlook, Teams and an ERP or accounting client resident at once. The 512GB NVMe SSD removes the other common source of waiting — cold boots, application launches and file copies all complete in the time it takes to look away.

Integrated Intel UHD graphics drive multiple displays for spreadsheets, dashboards and document work. This is a productivity and office machine rather than a workstation: it is not intended for GPU rendering, 3D CAD or gaming, and there is no discrete graphics card.
