Re: Yet another form factor?

I do know that Purcell Brackets has the bracket. I've been designing cryptocards
for 2U boxes for over a year using the Purcell Bracket number P163-0000. The guy
at Purcell told me he was on the steering commitee for the Low Profile cards...

http://www.purcellbrackets.com/. Take the link on the front web page that says
Low Profile PCI (http://www.purcellbrackets.com/lp-pci.htm). I think these match
the PCI ECN spec...

One thing you do have to watch for is the height the box maker actually uses for
the motherboard standoffs in the 2U chassis. I've noticed that some are a bit
tall and cause the card to sit wrong...

More and more I'm seeing PICMG cards in single-U racks. These usually use a
passive butterfly backplane...
