Not really much to worry about so long as the box is within physical reach.

A Core-2 Quad with decent RAM complement builds <whatever> fast enough that 
multiple installs and rebuilds in the same day are nearly painless.

What you might want to do is keep a local backup copy of the sources and ports, 
rotate & refresh that periodically so you are not at the mercy of your net link 
or potentially heavily-loaded mirrors to go forward, backwards, or 'sideways'.
