Then you deal with it when you get back. Easy as that. If it is non-critical enough to turn off when you leave the house, then it is non-critical enough fix it later when you have time. Fixing software/bios/program errors are not time-sensitive.
Hardware now is EXTREMELY safe and it has to be tested against electrical surges, ESD events, and depending in the device, different temps in order to get CE conformity and UL ratings. There is a near-zero chance that it would cause a fire or something critical, especiallly because home servers typically are not under load most of the time.
