Received my HAS the other day so far so good. I am using this HAPP PSU:

I know that some people had concerns about having the exposed mains power terminals(as did I). Due to how my MVS is situated(inside the belly of a coffee table), I was a little worried about my own fingers accidentally turning me into charcoal let alone my kids. I was able to find a sterilite organizational container that fits the HAPP perfectly(11in x 6 5/8in x 2 3/4in). I drilled a couple holes in it for the cabling and it came out pretty good. I'm no electrician but I think this should provide for my safety and allow me to move it around without dying. It also leaves me room to add ventilation holes if needed.
I tied a small simple knot in the power cord to keep it from yanking on the terminals.
I thought I'd share this in case anyone was looking for ideas. I wasn't looking for Ft. Knox but just something to keep stray fingers or pet paws from causing problems.
