Learning to assemble can help you to get to Manufacturing side of jobs in PC companies.
Other than this as you upskill yourself you would be able to get yourself into Cloud companies as well
In fact, there are may different kinds of hardware, e.g. Servers, Storage, Network equipments, notebooks, desktops, etc. All of these may have require different knowledge and skills.
I suggest you can take the Computer Engineering course in the college first. The course will provide you an overview on the computer architecture and understand how the hardware works. The course can help you to prepare to be the engineer on these platforms. You can also decide what area(s) you have interest on.
On the other hand, the openings on the hardwares usually with the vendors or manufacturer. You can seek for the intern opportunities to work in these corporates. This can help you to determine which platform you have interest to develop your career.
Hope this helps! Good Luck!
