What the differences mean

Operating system

The Asus Chromebox 5a runs ChromeOS, which removes most fleet maintenance and supports Android apps through Google Play but cannot run native Windows software. The Geekom A5 Pro runs Windows 11 Pro.

Memory and storage capacity

The Geekom A5 Pro ships 16GB of dual-channel DDR4, expandable to 64GB, and a 512GB drive. The Asus Chromebox 5a ships 4GB of single-channel memory, expandable to 16GB, and a 128GB drive.

USB port count

The Asus Chromebox 5a has seven USB ports, dual HDMI 2.1, DisplayPort 1.4 and a micro SD reader, plus Wi-Fi 6E and Bluetooth 5.4. The Geekom A5 Pro has six USB ports, dual HDMI 2.0, two USB-C outputs, a full SD reader, a Kensington slot and 2.5G Ethernet.

Networking

The Geekom A5 Pro has a 2.5G Ethernet port. The Asus Chromebox 5a has Gigabit Ethernet only, though it makes up for it with newer Wi-Fi 6E and Bluetooth 5.4 radios.

Which one to buy if

  • the deployment is a managed fleet of browser-based workstations
    Asus Chromebox 5a (Celeron 4GB + 128GB)

    The Asus Chromebox 5a's ChromeOS updates itself in the background and is managed from the Google admin console, at a lower price.

  • you need to run Windows software day to day
    Geekom A5 Pro (Ryzen 5 16GB + 512GB)

    The Geekom A5 Pro runs Windows 11 Pro natively, which the Asus Chromebox 5a's ChromeOS cannot do.

  • you want more memory and storage headroom out of the box
    Geekom A5 Pro (Ryzen 5 16GB + 512GB)

    The Geekom A5 Pro ships 16GB and 512GB against the Asus Chromebox 5a's 4GB and 128GB.

  • the desk needs the most USB ports and the newest wireless radios at the lowest price
    Asus Chromebox 5a (Celeron 4GB + 128GB)

    The Asus Chromebox 5a has seven USB ports, Wi-Fi 6E and Bluetooth 5.4, all for less than the Geekom A5 Pro.

What owners say

Geekom A5 Pro (Ryzen 5 16GB + 512GB) owners describe the everyday desktop role exactly as advertised: streaming and web browsing, running Adobe Photoshop daily in a small business, email and office work, even light CAD alongside 3D printing. Setup keeps coming up as painless, quick, with no bugs and no bloatware, running Windows 11 Pro cleanly out of the box, and the combination of small size and adequate speed gets called compact, cheap and functional, with one owner buying a second unit for the office after the first worked out. Support experiences skew positive, including an owner escalated to senior technical staff within a day for a Linux boot problem. The trap several owners flag is storage: unlike the standard A5, this Pro variant has no 2.5 inch SATA bay, only M.2 slots, so reusing an old drive means an external enclosure, and the integrated Radeon Vega 7 graphics are fine for display and video but not gaming.
