Are there any known problems associated with long term storage of artifacts, prints, stringed instruments, costumes, etc. in rooms adjacent to a large computer data storage area.  The room was built in the 1970's to handle the computer technology of the day but now, as technology have led to smaller devices there is a large amount of free space.  It seems a good idea as the temp/humidity demands of both the computer devices and the archives are similar enough to be manageable but am wondering if anyone else might be in a similar space or know of any dangers that I'm not aware of.
