>whats your build like?
I have a mItx generic N100 mobo, a cheap 80+ bronze sfx power supply, more ram than the dinky CPU on my motherboard can likely properly use, a fully 3D printed case (excluding fasteners), noctua fans, and 2 8tb Toshiba nas drives + low power draw OS NVME. Using Openmedia vault for my OS, works alright.
>do you run it 24/7?
For the past few months, yea.
>should energy/power requirements be factored into it?
Definitely should be considered, given modern energy prices. Many low-power friendly options out there, but you have to be careful- for example the N100 supports crazy low idle power use in theory, but nearly every Chinese board does something to make that feature not work properly.
Only advice I have is get something that supports a large enough pcie slot to allow you to use some sort of HBA card so you can use cheaper SAS drives.
