Best way to remotely access pc on same LAN

Hey guys. I have a steam link I’ve used for quite some time. But I’m wanting to figure out a solution that is similar but grants full PC control. I have my main PC hardwired and a steam link and monitor out in my garage I’m routing to with a power line adapter that works pretty great. But it has a lot of issues when minimizing steam to use as a full PC. I have a mini pc N100 I planned on using as a router. But would be happy to swap to use for this if possible.
