Thank you very much, that was the kind of advice I was needing. I was looking into the Moog racks but I was concerned about depth. And I don't understand why they are so inexpensive... I realize they don't have power, but I look at how much a power supply costs and I can't figure how an unpowered case goes for $50 and a powered case goes for $350.
Also, did you mean to suggest those other modules INSTEAD of the Pam's , or to add to/augment the Pam's? Good info, tho thanks again.
