I've setup many bitcoin ndoes in the past, mostly running linux and it is fairly simple to do if you follow the instructions online and use a vanilla flavor linux distro.

That said, if you just want to run a node to have wallet and a node to verify transactions for your wallet, you might want to just install a node on a Windows machine as the GUI there will make things much simpler. Depending on your HDD space and time you intend to keep the node online, you might want to run it in a pruned mode to save on disk space. The initial download of the blockchain is needed as well and will be the thing that takes the most amount of time (anywhere from 24hr to a week).
