Indeed I do. I see you've heard the story of PSINet melting components as  
well.

We used USR(3Com) TotalControl hardware: vertical venting. The chimney  
effect was impressive. (65F in, 100+ -- sometimes 120 -- out.)

(I've complained for over a decade about $DAYJOB building crap with  
side-to-side venting.)
