If it isn't hampering you, I wouldn't mess with it, but
But it's the hubs I wonder about--two old
National Semi 6-port Datamover 10BaseT units coupled together with a
10Base2 (coax) link. It's that coax that I dread replacing--it goes
between floors and snaking it through the walls was a real chore.
Keep in mind that this time around it won't be so hard- just attach two
nylon strings to the
coax, pull it out, attach your fiber or UTP to one of the strings and
pull it up. Leave the
other string in the wall if you ever need a second line.
