   At one time ; many years back, I had picked up a over 100 of these huge heavy   
   boxes, mostly early versions of the 386 mod 80's  from  back then; National   
   Grid from upstate NY,, In Syracuse, Most of them had severe hard drive damage   
   in the old aluminum    
   cased seagate hard drives that were installed in them,  St-506's or 225's or   
   something.   
   huge media failures  from spin rite.....  some internal shredding   
   platens...lots of the floppy drives had the little foam rubbers from on top of   
   the heads floating around inside them.   
   The sound barrier  foam on from the covers falling in on them, making a goey   
   mess..no locks and keys..  I barely got my money back selling them for scrap   
   or parts..   
   Lots of  mother board failures .  I didn't spend a lot of time with them..  I   
   still have many of them in the warehouse.. I still use them for shelf   
   uprights  on 2x8 planks   
   they are very stable with the feet spread out... At onetime I had thought   
   about using them; Filled with concrete, for a retaining wall...
