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.)
