And I don't even use most of them

I used an old laptop I had with a broken screen. Werks

I used to have my own server for 4 years. It was my personal compute with virtual machine and 10TB. Then I checked my electricity bill, it was so expensive I rebase everything on a single RockPro64 with a raid 1. Hardware budget is not that expensive, but you should definitly calculate how much electricty will weighs on your house budget
