I have a DELL tower built in 2011 that I frugally installed Tahr-6.0.5 (32 bit) in 2013. I installed avahi-daemon
in 2014 and the hplib pajkage to get the HP printer drivers. The system is mostly for acting as a print and scan server that Android and Apple devices can print directly too.
I have not updated anything on it since 2018 when I removed most of the browsers which are not needed on this system. Runs solid as a rock wall and is amazing how well it chugs along doing everything printer.
Never had a single problem with security so far in all of this time. The system is LAN/Internet connected and I am using it now to print package address labels. The 32 bit Tahr runs and runs......still a favorite of mine.
