FreeBSD performs well, even on older hardware. I have used it to continue using older hardware that would have otherwise been disposed of. It is secure and robust. It has excellent package management (pkg) and a large collection of ported software from Linux. Documentation is excellent (FreeBSD Handbook). Review collected by and hosted on G2.com.
Installation can be tricky for first-timers; you will probably need some experience with Linux before trying to use FreeBSD. You need to be comfortable using a command-line terminal most of the time. Review collected by and hosted on G2.com.
