Seconded to most of these posts: buy a old/used cheap laptop from FB/Craigslist, wipe it clean with a fresh install (Linux preferred, but Windows works) then install Bitcoin Core directly from the website. Plug it in somewhere, make sure it stays on, and you're done. Full dedicated Bitcoin Core server in your house.
Thanks, I guess this the path to follow. What will be the minimum requirements RAM, Hard Drive, etc?

16GB and 2TB more future proof

You can prune the blockchain down to 2GB, I believe. That's something you'll select during the setup process when installing Bitcoin Core. RAM, I'd say 4G is minimum, but you'll want at least 8G imo.
