Running Node for 1st time and feeling so proud

after wasting years on Shitcoins , I learnt about bitcoin , learning things little by little on how BTC works . When i came to know that we can just download software and start Node , I immediately decided to run node to help making network more decentralized ( humbly dont know yet if mining make it decentralize or running node or something else ) . But i doo have one question . I usually keep my laptop off at night , Is there any hardware device also which is like plug and play to router or network to make it run 24/7 . Sorry for my poor english .
