HP ProDesk 400 G4 Mini Desktop

This compact desktop runs Windows 11 Home on a hexa-core i5-9500T processor with 8GB of memory and a 128GB SSD. It suits home users and office workers who need a space-saving PC for everyday productivity tasks. The mini form factor fits easily behind a monitor or on a small desk.

Integrated Graphics and Memory Limits

The system relies on integrated graphics, so it handles general business applications and video playback but is not suited for 3D rendering or modern gaming. Memory can be expanded to a maximum of 32GB across two slots, giving room for heavier multitasking if required. Buyers who need discrete graphics performance should look elsewhere.

128GB SSD Primary Storage

The 128GB solid-state drive provides fast boot and application loading for the operating system and core programs. Users with large media libraries, extensive project files or multiple virtual machines will find this capacity restrictive without adding external storage. Buyers who want more internal storage should consider other options.
