[mythtv-users] OT Watercooling was Gigabit switch

[Mark]

Sorry,  I just assume everyone knows what I'm talking about.  :)
I could draw a diagram later and send it to you.  The pumps could be had
either off the shelf or in junkyards.  You might also check with 
aquarium suppliers.
I know that pumps for water cooling traditionally are aquarium pumps, 
but I don't
know if they are magnetic drive.  with that much hardware, you don't 
want a leak... :)
