Software for remote access, for games?

Question

Remote access

Good afternoon.
Input data:
There is a family of several people who sometimes play, including planning in VR.
I want to buy a truly powerful PC and use our current PCs as thin clients.
I want to make something like a playkey cloud gaming service, but for home use on a local network.

Tell me, maybe there is already a ready-made solution for such purposes?

Google does not give anything intelligible yet

Important addition:
The target will connect via a grid (gigabit) to the station from thin clients, without noticeable lag
