You can go down to literally a usb stick or even micros card if they support it. Esxi works on an SD card with a few config tweaks.

What is your job? Do you have exposure to life cycled hardware?
Too long
You'll need inlet and outlet, not just outlet. Also, look at your server power usage too, drive don't generate newrly a much heat.
Yes because they're cheap.
Doing it for the experience and lab of it? Sure.
Doing it to actually use, fuck no. Email is the most vulnerable part of any org. You need to have a proper spam filter, dmz, web domain, several DNS records, certificates etc in order for mail to even flow in and out. It'll just be a headache and there are so many free options.
If you want your own special email domain, get suite for 1 person at 12 bucks a month and have it all just work.
Why make it complicated? Throw an ssd and at least 8gb of ram, should be fine to run windows 10.
Are you going to update the firmware upon every release? Are you going to monitor for vulnerabilities?
TA have automated software that will find it, and mess with it for funsies
Could the Ilo have died? Was it known working before you took over the system? It's rare but any tech can fail.
Do you have activity on the interface?
Don't worry about it, no one wants to hack your plex server xD just don't expose things directly to the internet and you'll be fine.
Nas software is more friendly and just works. Windows doesn't have a great raid option, but nas do. Windows desktop also has alot of artificial limits and is less stable and will reboot for patches at inconvenient times.
I simplest terms, it's like use a flat screw driver on a Philips head. It'll technically work, but there are just plain better options that will work better and easier.
Not without alot of messing around, I'd just stick with 2.5.
