Is the i5-12400 fast enough for everyday use?

Yes. Its six cores and twelve threads handle browsing, Office, video calls and light photo editing without lag. Heavy gaming or 4K video editing will feel slow because it relies on integrated graphics.

Can I upgrade the RAM and storage?

The Pavilion tower has accessible memory slots and room for an extra drive in most configurations. Check the exact board layout before buying parts, since HP sometimes uses proprietary connectors.

Does it come with a monitor or keyboard?

Typically no. This is a desktop tower only, so budget for a monitor, keyboard and mouse unless a bundle is specified.

Only light or older titles at low settings. The integrated UHD Graphics 730 is not a gaming GPU, so a dedicated card or a different machine is needed for modern games.

Is it good for a small office?

Yes. It is quiet, compact and handles office suites, email and video calls. For many users at once or heavy databases, a faster model with more RAM is better.
