What are you guys even running that needs to be on?

I just got a Dell R510 and a HPe Proliant 360 g7, installed esx on them, but i cant find anything that would justify running them for 24/7.

I mean, besides a nas that holds some files.. i cant find anything worthy.. can only think about enterprise purposes which i dont meed at home.

So, to answer the question, they are always off untill i want to experiment
