Is the 400 G9 DM i513500T compatible with DDR4 or DDR5 memory modules, and what type of expansion slots does it support for additional peripherals?

The HP Pro Mini 400 G9 Desktop Mini PC with the Intel Core i5-13500T uses DDR4 memory modules. It supports DDR4 RAM, which is common for many business-class mini PCs and balances performance and cost. As for expansion, it typically includes M.2 slots for SSDs and USB ports for peripherals, but it doesn't have full-sized PCIe slots for larger cards like standard desktop towers do. If you're planning to add peripherals beyond storage upgrades, you’ll likely rely on external USB options or Thunderbolt, if available, since internal expansion is limited by the mini form factor. For more extensive upgrades or adding discrete graphics, a larger desktop with full PCIe slots would be necessary.

What is the operating system of the HP Pro Mini 400 G9 Desktop Mini PC?

The HP Pro Mini 400 G9 Desktop Mini PC runs on Windows 11 Pro.

What type of storage does the HP Pro Mini 400 G9 Desktop Mini PC have?

The HP Pro Mini 400 G9 Desktop Mini PC has a 512 GB PCIe NVMe SSD.
