Whether you're setting up a new office, upgrading your workspace, or deploying across your team, the ProDesk 400 G9 offers serious performance in a compact small form factor — without compromise.
HASSLE-FREE WARRANTY
This HP ProDesk 400 G9 system is backed by a 1-year warranty that protects you against electrical and hardware component failure. Should your system experience a hardware-related issue within the first 30 days, you're covered by our standard Collect & Return service, ensuring quick and convenient support.
After the initial 30-day period, a fully qualified technician will be scheduled to assess and resolve any hardware issues. This can be arranged at your convenience, either remotely or by visiting our London store.
In the unlikely event that a repair cannot be completed under the warranty terms—due to unavailable parts or if the repair cost exceeds the original value—you’ll receive a brand new replacement system with matching specifications.

ABOUT HP PRO DESK

Part of House of Computers, the HP ProDesk 400 G9 is a powerful, business-class desktop built with the same dedication to quality and performance that defines our custom systems. Every unit is assembled using brand new, genuine components and thoroughly tested by our experienced in-house technicians. Unlike mass-produced systems, nothing is imported pre-built — we build and check every ProDesk on-site to ensure it meets our highest standards. That’s what sets us apart.
We offer a wide selection of pre-configured business desktops to suit different workloads. However, if you’d like to upgrade memory, storage, or other components, customisation is easy — just choose your preferred options or connect with our live chat team for assistance. Need something fully tailored? We’re happy to build a solution from the ground up based on your exact needs.
