Is the MSI PRO 23.8 good for gaming?

Only for light or older titles at low settings. It uses Intel integrated graphics, so modern games will run poorly. A tower with a dedicated graphics card is the better choice for gaming.

Can I upgrade the RAM or storage later?

All-in-ones are harder to upgrade than towers. Some MSI models allow memory and SSD changes, but you should confirm the specific configuration before buying. Plan on the 32 GB and 1 TB lasting the life of the machine.

Is 32 GB of RAM overkill for office work?

For basic documents and email, yes. It pays off if you keep many browser tabs, spreadsheets and apps open at once, or run virtual machines. Most office all-in-ones ship with 8 to 16 GB.

Does it come with a keyboard and mouse?

Yes. MSI includes a wired keyboard and mouse, so the system is ready to use out of the box.

Is the 23.8-inch screen good for photo and video editing?

It is fine for casual editing, but 1080p at this size is not sharp enough for detailed color work. Serious editors should look for a higher-resolution display with better color coverage.
