I don’t think you have to worry about security with old(er) computers that have been reassigned to be a server. You’re going to most likely be running an up-to-date Linux OS, and as long as you keep everything updated, you shouldn’t have any issues. Couple that with security deployments, and I think you will be good.
The problem is that very old computers are not as efficient when it comes to electricity to run them. Will it run your power bill up an extra $100+/month. Probably not. I would stay clear of old enterprise equipment because they definitely are power hogs. It really depends on how expensive electricity is in your local. For me, it’s relatively cheap. I think I saw an increase of about $25 which is probably a nominal amount that most people would spend on a hobby.
I noticed this watching a solar powered gaming build. Better to run faster hardware slower than slower hardware faster for power conservation. The base minimum will be higher but the increase in requirements will rise slower.
