Is the HP OmniDesk good for everyday work?

Yes. Core Ultra 5 with 16 GB of RAM handles browsing, Office, video calls and light photo editing comfortably. Choose the Ultra 7 and 32 GB if you keep many apps open or work with large files.

Can I upgrade the RAM and storage later?

The tower models generally allow RAM and SSD upgrades; compact models are tighter and sometimes use soldered or single-slot memory. Check the specific configuration before buying if upgrades matter to you.

Does it come with a monitor, keyboard or mouse?

No monitor is included, and bundles vary by configuration. Plan on buying a display, keyboard and mouse unless the listing states they are bundled.

Only lightly. It relies on Intel integrated graphics, so esports titles and older games run at modest settings, but modern AAA games need a dedicated GPU, which this desktop does not offer.

What is the difference between the tower and compact versions?

The tower has more room for upgrades and airflow; the compact saves desk space but limits expansion. Both use the same Core Ultra processors and DDR5 memory.
