John,

Indeed, but not very serious either... however you said:

Ah, some usefull info for a change! Albeit it is somewhat too
compressed. Also, didn't you mean to write 3HE high or?

Althought I have been reading alot in rack standards I haven't read
much about subrack standards.

A serious question (I have the answer, but do you?):
How much effect was the fullsize rack standard designed to handle in
heat dispantion through convection?
That is, if you have a full 2 meter high 19" (or 600 mm metric rack)
full of equipment, how much effect may we "burn" in that equipment.

I've broken that limit, and so has many others, but do you know how
much it is?

Oh, was it Doepfer smashing? I was just into general hand optimization
of size ;O)

John, thanks for the serious info.

Cheers,
Magnus - likes jokes, but apprechiate good info
