a good computer recommended to me

I want to buy a new computer.

dont buy better ps5 i thought

how much is your budget?
if it is good you should get the 12th generation processor and 32 go of ram and a 1to ssd m.2
and a 3090 graphic card
You dont need to upgrade at least in the next 5 years

If you want to use so many PC equipment you can also buy rack for it. If yoi live in Canada or USA through this site https://sysracks.com/, for example.
