I did this first time I downloaded core wallet but it was on laptop an old one from 2007 and it was a nightmare, I even liked banning people and used to ban those nodes with old version wallets and wallets other than core. I thought if I run a node then I can receive tx fees but nothing ever happened
.
That is my initial thought too, running it on an HP Probook 6555b with a replacement hard drive of 250gb just to suffice with its requirements way back 2015. After a few weeks of running it (and a few notices from my ISP that I have exceeded my upload bandwidth or whatever that broke our ToS), I considered stopping it and put the poor laptop to rest. Haven't read well enough on the matter back then so I thought I was a hero by running that laptop on 24/7 but realized I was only wasting my time and money for the said project.
But still, given the risks and problems I might face for running a full node right now, after understanding everything, I would be glad to run another one once more.
