Overview
A small office desk gets a compact desktop with an Intel Pentium Gold processor, integrated graphics and Windows Pro, with a wired keyboard and mouse in the box. Front and rear USB ports, Ethernet, HDMI and DisplayPort cover most office peripherals.
Suits office work, classrooms and home admin with a very full port set and upgrade room for memory and storage. The title mentions a Core processor, but the specs list a Pentium Gold part, which is a more modest chip.
Who it's for
Offices, schools and home users running web, documents and video calls on two monitors. Gamers and creators who need a stronger processor or dedicated graphics should look elsewhere.
Pros and cons
- Compact small-form-factor body
- Many USB ports
- Dual 4K display support
- Upgrade headroom for memory and storage
- Integrated graphics only
- Older USB 2.0 ports at the rear
- Title and specs name different chips
Performance notes
The Pentium Gold processor handles web browsing, documents and video calls. Integrated graphics drive two displays but not demanding 3D work. Memory and storage can be raised to the stated maximums, which extends useful life. Front and rear ports reduce the need for a hub.
