Compact Mini Desktop for Office and Home Media

The HP EliteDesk 800 G3 Mini is a ultra-small desktop PC powered by a quad-core Intel Core i5-7500 processor running at 3.4GHz up to 3.8GHz. It ships with 8GB of DDR4 memory, a 256GB NVMe SSD for fast boot times, and a 1TB hard drive for bulk storage. Windows 10 Pro is pre-installed, making it ready for business tasks, home office work, or a media server setup.

Upgrade from Older SFF or Tower Systems

This Mini replaces bulky small-form-factor or tower desktops when desk space is tight and silent operation matters. The jump is worth it if you need a near-zero footprint behind a monitor, dual-display support via DisplayPort and VGA, and the responsiveness of an NVMe boot drive. It also adds modern wireless with Wi-Fi 5 and Bluetooth, plus gigabit Ethernet for wired reliability.

Check Power, Mounting, and Expansion Needs

Verify that the included 65W power supply meets your peripheral load, as the Mini uses an external adapter. Confirm your display accepts DisplayPort or VGA input, since no HDMI port is present. The tool-less chassis offers two SO-DIMM slots, one 2.5-inch drive bay, and an M.2 socket for future storage or memory upgrades.

Questions about this item

What physical space and mounting options does the HP EliteDesk 800 G3 Mini require?

The ultra-small Mini chassis fits in tight workspaces and can mount behind any compatible Elite Display for a near zero-footprint setup.

How is the tool-less case opened for upgrades, and what step do people often miss?

The tool-less design allows easy access to two DDR4 memory sockets, a 2.5-inch drive bay, and an M.2 SSD socket; the step often missed is ensuring the chassis latch is fully released before lifting the cover.

What maintenance or replacement will the 256 GB NVMe SSD and 1 TB HDD need later?

Both drives are user-replaceable; the NVMe SSD occupies the M.2 socket while the HDD uses the 2.5-inch bay, so either can be swapped independently when capacity or speed demands change.
