I'm thinking of making an oak card cage for my 18 S100 slots. I've got the
original IEEE-696 physical parameters, is that good enough for all modern
N8VEM projects?
Nice thick oak to be non-flexible. Thinking a short "U" with the board at
the bottom and slots cut in the arms. Probably not coming up all the way
on the side of the cards. That rather firmly bolted to standard rack mount
shelf (heavy duty) bolted inside a steel rack case
Poly coated on all surfaces for humidity stability and it'll live in a
stable climate controlled area at constant temp/humidity anyway.
Will live inside a ventilated steel chassis I have access to for EMI/RFI
whatever. Thank you PCI/DSS financial regulations for forcing the
production of cool little networking device cases with great ventilation
and locks and access on all sides etc.
I have more than enough 'leet table saw skills to pull this off.
I'm thinking of two MBs one on top of another in the rack case. I've got
12U of space to hold these two MBs which will make a tight fit vertically
but probably survivable (Will have to model that extensively, maybe I can
get access to a 16U case...)
Crazy? Sane? Better idea? I can' t be the first guy in 40 years to think
of oak as a card cage material. Also are all the N8VEM cards under the
IEEE size standards around the perimeter? I've seen some mighty full cards
with "stuff" right up to the edge.
Curious if anyone tried it and the tannins in the oak made their pcb
corrode or poly finish sticks to rosin flux or something I haven't even
considered yet.
