Can I connect this desktop to Wi-Fi?

Not on this configuration. It lists no Wi-Fi and no Bluetooth, so you need an Ethernet cable or a separate USB Wi-Fi adapter.

Does it come with a monitor or keyboard?

No. The monitor is not included, and no keyboard or mouse is listed, so budget for peripherals.

Is the Ryzen 5 220 fast enough for office work?

Yes. With 16 GB of DDR5 and a 512 GB SSD it handles email, spreadsheets, browsing and video calls comfortably. Heavy gaming or professional rendering is not its job.

Can I upgrade the memory or storage later?

HP's compact business desktops typically allow RAM and SSD upgrades, but confirm the open slots and drive bays for this exact model before buying.

How does it compare with a Dell OptiPlex Micro?

Both are compact business desktops with Windows 11 Pro. This HP gives you DDR5 memory and a Ryzen 5, while many OptiPlex Micro units ship with Wi-Fi built in, which this one lacks.
