current uptime of my server
That's not a server, it's barely moving packets.
Now this is a server moving packets
Screenshot taken on July 1st, the server ran without a reboot until our friend Fances decided to kill our power for 4 days.
I have my personal laptop on for 60 days or more without a reboot.
If you a enough cooling on your system, then it's actually better to leave your computer on (as long as you have good surge protector and UPS). But in reality leaving it on doesn't extend the life of the computer all that much, IMO.
At worst, you screw up and die.
