I have a HP microserver N36L that I use as my home NAS for last few years. It's still going strong, my uptime is usually 2-3 months. Sometimes the power needs to go off, right now it's sitting at 29 days. Like you've said I only reboot when I feel that all other solutions have failed. My daily driver docked T430 gets shutdown when it's not in use but I often leave it on for days at a time, swapping the battery for the 9 cell if I'm on my way to University.
