Hi Guys, Me again

Been posting here a lot lately, lol but thats cuz yallz are so damn helpful each time

So I am currently using my Old HDD in an otherwise entirely new computer.
I have a 500GB SSD still in the box.
my goal is to use the SSD as a boot drive with OS and Games. Everything else on the Old HDD.
Would prefer to keep my current OS if possible.
Question is, what is the best way to make this happen?
Thanks guys!
Edit - P.S. if it simplifies things, completely willing to do a factory wipe on my current HDD
