> As two 6u racks next to each other. That would be an instant buy!

There are no plans to add other types of A-100 cases for the near future. We
have already more than 10 different cases available (A-100G6, A-100P6,
A-100P9, A-100LC6, A-100LC9, A-100PMS6, A-100PMS9, A-100PMS12, A-100PMD12,
A-100PMB, A-100MC raw, A-100MC black) and we already have problems to stock
all types (apart from the problems for our dealers). We discovered that the
sales of the 9U cases increased during the last few month (P9, LC9, PMS9) as
these have the best value for money because one PSU is combined with three
bus boards. But you may built your own low cost 12U rack by means of two
A-100 DIY kits #1.
