I'd like to repurpose the All-in-one chassis. It's got a 24" touch screen and there's a member of the family who has a special need for the touch screen and who might struggle to get to know a new and unfamiliar machine. We're using it for web browsing, and Microsoft Office, primarily, I'm not trying to build a gaming monster, just trying to bring it into this decade.

It runs on Windows 10 and is coming to the end of it's usable life.

I believe I need to replace the:

Processor which is an AMD Ryzen 5 2500U with Radeon Vega Mobile Gfx 2.00 GHz

Installed RAM 8.00 GB (6.93 GB usable)

I've looked at what the current product category equivalent is from HP and it's probably the HP Envy Move All-in-One 24-cs0019 All-in-One PC which runs on Windows 11 and has

Processor: Intel® Core™ i3 1315U (13th Generation)

Memory 16 GB RAM

but I've never explored the inside of an All-in-one and I expect I'll encounter at minimum a more difficult space to work in than a standard PC tower. Please if anyone with experience with this kind of thing can tell me if this is going to be practical or if there's some tricky quirks I'm bound to run into, I'd really value any expertise you might share.
