Henry,

I don't have one of those, but if you go to 
http://www.mp3car.com/vbulletin/ and search you'll find people who have 
used that supply (and a number of similar supplies as well).  From what 
I remember I think the reviews have been mixed.  It seems like the Opus 
brand supplies have a better reputation. I've got an earlier Opus and an 
M2-ATX.  My Opus failed due to user error, and so far the M2-ATX I got 
to replace it when I needed one fast seems OK but it gets mixed reviews 
as well.  It apparently has a tendency to fry motherboards when it 
fails, so if the M4 has a similar design it may have the same issue.  A 
set of hpsdr boards costs a lot more than my mini-itx motherboard.   The 
mp3car store (I have no connection other than buying a few things and 
being a forum member.) sells several models of supplies like that since 
they're popular among people making their own in-car PC but they may not 
be a convenient source depending on where you live.
