Putting a voltage converter in a project box

Scotch Indoor Mounting Tape comes in 1/2" and 1" widths.  It's padded and double sided.

Ace Hardware and Home Depot stock it.

I'd mount it with self-adhesive Velcro strips so you can pull it off if necessary.  You can buy the stuff at Home Depot, it comes in rolls with both sides on the roll.  Cut off what you need and stick it on.  I keep this stuff in black and white around: 15 ft. x 3/4 in. Sticky Back Tape

The big box hardware stores can have limited selection making you buy a roll or whatever.  You only need a few inches of whatever mounting tape/velcro.  If you have a craft store near you like Joanns or Michaels you can buy small packages of the stuff and print a 40% off coupon from their website or from Sunday paper.

Stan, you can buy a smaller amount at HD as well, but once you have the stuff around, you'll find all sorts of uses for it!   I use it to secure boards in upgrades, that makes it easy to pull them out if I need to without cleaning off old glue, etc.

GRJ,  Have you "standardized" on whether the circuit board or host surface gets the hook-loop side vs. the fuzzy side?

I usually put the fuzzy side on the board and the hook-loop side on the chassis.  That's just arbitrary, but I do that unless there's a reason not to.

I just remembered I want to chime in on this a bit more.  As for Velcro, may be too thick for the height.  I thought I had a half inch to spare, but forgot to include the height of the solder points on back of board.  I have both Velcro and double sided tape, but have not yet checked to see if one is thicker than the other.  Either one, when placed, will more or less be permanent.  Can't imagine trying to slide the board horizontal to remove it, but I can't see needing to.  If the board fails, I will simply scrape it out and put a new one in. 

Another consideration is the four wires.  They will have to be connected to the board prior to placing it into the box.  So will need to drill hole(s) for them.  I might drill one hole and feed them through together.  Then there is the issue of sharp edges created by the drill bit.  Anything I'm missing here?
