[Asterisk-Users] Number of TDM405 Cards in one server

[Michael at Matraex.com]

Has any one put 3 or more TDM405P or TDM410P cards in a single server?
I would like to fit as many as 6 into one box.

I am concerned about several things such as power requirements and the
amount of cooling as well as CPU and memory utilization.
Is there a difference in the power consumption and heat between the 5.0v
and 3.3v boards would one be better than the other for such a dense
situation?
I have not been able to find any recommendations from digium on this
side of things.

Has any one implemented this in the past and what did you have to worry
about.  
What type of motherboard/system/memory/cpu did you use or what do you
think would be best.
I get to start from scratch on this but I would like it to be as dense
as possible since it is going into a Colocation Rack at a data center
and space is money.

Thanks
Michael
