I am attempting to make a hacked together cyberdeck and I was curious if there were any groups that could help

More specifically it is the meaning closer to what older media in the Cyberpunk genre considered a cyberdeck that is cobbled together from a bunch of different pieces and parts not just a rasberry pi in a cool case with some ports added(cool as they may look in wanting something made from random components and computers I had laying around partially to reduce ewaste partially because it would be cool to have)
