At the moment I am eliminating a large section of shelving so I can build a
machine room on the side of the office inside the shop.  I want to drop the
temperature around my machines so I am less likely to fry computers.  I've
run the last several summers without air conditioning the machines, but
these computers were never really intended to run in an Arizona warehouse in
the summer.  After that is done the outside walls of the machine room will
get shelves again.
