Remember the Ascend MAX TNT and the sideways left-right airflow?

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.)

We used Livingston Portmaster 3 back in the day. Front to back
ventilation, ran cool as a cucumber, plug it in and it just worked.
Awesome gear until Lucent bought the company to kill the product in
favor of their Ascend TNT space heaters.
