Yes, for the lower end of the market you won't find that capability
built in, but going forward - if you're looking for a server that is
going to be co-located then remote management built-in should be one of
the things at the top of the list of requirements. The iLO / DRAC still
works as a very good option, especially if you don't know what equipment
the engineer will bring onto site... you can at least expect them to
have a laptop with a RJ-45 port on it!
