If you have any APC Smart-UPS units with open expansion slots, APC
sells a gadget that provides ambient environmental monitoring. I
think it's called "Measure-UPS". I'v
magnet to the pointers,
and thermal-glue reed switches in strategic places - and you can set up
limit-sensing, which may be all you need.

Oh and for reference a single temp point + single humidity point would be...
$424 + S/H (about $8) - can be expanded to 4 T/H points, hackable for
switch closure etc.
Save you shipping and handling if we meet somewhere for you to pick it
up; company is in Bow, NH, I live in Merrimack, NH.

http://www.midondesign.com/index.html has a box w/ temp & humidity
sensing to serial port for ~ $135. They also sell the parts so you

It's probably worth mentioning that most motherboards built within
the past 5 years or so have some capabilities for monitoring. Most
have at least one temperature sensor. If all you're interested in is
making sure your equipment isn't overheating, this will often do the
job.

I believe (as I had responded privately to the original

I2C or close enough to work with things like the LM34 and TCN75A (I
like MicroChip) and other I2C temperature sensors. They tend to be
SMT, but you can get things
