Extreme cold will damage LCDs--I live in NH, and lost an IXO handheld
terminal that way. At my previous home, my storage was similar to what you
describe. Also, the heat of an attic will warp some plastics, and I suspect
that it accelerates the yellowing process. I didn't have a problem with
circuit boards, however. Hot and cold extremes will not be kind to software
or to some types of paper. Temperatures aren't the only thing you have to
worry about with the type of storage you describe. Vermin (insects, spiders,
mice, bats) will also be a problem. I kept my stuff covered with old
blankets and tarps to cut down on damage from dust and droppings. The
coverings will also help with certain weather conditions common to New
England. In springtime when the humidity is high and the temperature rises,
moisture will form on metal and plastic surfaces.

Subject: Cold/Hot storage of computers -- OK?
  Hello all,
 Since I am rapidly exhausting all space in my basement workshop, I need to
 move some of my computers to the loft above our garage.  The problem is, 
the
  garage is completely UNinsulated, and has only a metal
roof (i.e., thin, 
and
  NO resistance to temperature -- hot or cold).
 My concern is that the cold of winter or the heat of summer might get to
 them.  I live in Massachusetts, so winter is not -40 degrees F, but we 
are
  talking below freezing, and possibly below zero for
short stretches.  In 
the
  summer, it must easily hit 100 degrees F in the loft,
due to the hot metal
 roof, and the trapped air (no windows!).
 I'm not so worried about the circuit boards, but I am worried about floppy
 drives, hard drives, and CRTs.  Does anyone know if such temperatures will
 kill these things?  Obviously I would let the computer acclimate for about
 24 hours after I move it back into my house, to avoid sudden temperature
 swings, or condensation.  I'm more worried about the storage affecting
 them....
 Thanks!
