Is the HP Elite 800 SFF good for everyday office work?

Yes. The 14-core Core i5-14500, 16 GB of DDR5 and a 512 GB SSD handle email, spreadsheets, browsing and video calls without strain. It is not built for gaming or heavy video editing.

Can I upgrade the memory later?

Only within limits. HP lists a maximum of 16 GB and a single memory slot, so the installed 16 GB is effectively the ceiling. Buyers who need more should look at a model with more slots.

Does it come with a monitor and keyboard?

No monitor is included, and the box lists only a mouse. Plan on adding a display and keyboard unless you already have them.

Can it run multiple monitors?

Yes, through the Intel UHD 770 graphics and the available USB-C and USB-A ports. Check the exact port layout on the unit you buy before connecting two or more displays.

Is it good for gaming?

No. The integrated UHD 770 graphics handle office and media tasks but not modern games at playable frame rates. A desktop with a dedicated graphics card is the better choice.

The listed connections are USB-A, USB-C and RJ45 Ethernet, with no Wi-Fi mentioned. If you need wireless, plan on a USB Wi-Fi adapter or a wired network connection.
