By now, some people have probably noticed that I have a bit of a bee in my bonnet over cases...
First issue is that the snazzy ones, while pretty, tend to be rather expensive...at least compared to the Pi itself. It just somehow feels wrong to need to pay one third to one half the cost of the *computer* to get a case to put it in.
So I've been buying cases here and there to try them out. I have on hand (so far) an Adafruit case, some ModMyPi cases and, just arrived today, cases from MCM Electronics, a partner of Farnell. (Cases from RS are on order...and have been for 2 months.) Since these last are a fairly recent discovery that I haven't seen anyone talking about, I figure I owe people at least a preliminary review.
I spotted them on the MCM site after having searched Newark (the US sub of Farnell) and not finding any cases other than the "Bud" case, which I'm not interested in.
The cases from MCM came in a padded envelope, much like Farnell and Newark ship Pis. The cases themselves come in shrinkwrap--with a Farnell label and part number. I have since looked the numbers up on the Newark web site and they are there (the clear case is #2113799, the black one is #2113798, and there is also a white one). MCM's price is $7.35 each, and Newark gives the same list price, but they're on sale at the moment for a bit less at $6.62.
The cases are in two pieces of very smoothly finished plastic that snap together. Getting them open the first time takes a bit of doing, though. I was glad I started with the clear case, which meant that when I dealt with the black case, I'd already be able to see what I was dealing with. Since the cases don't come with directions one just has to cope. The Pi is held in place in the bottom of the case quuite firmly by edge clips that you snap the Pi into. External connecters have good support as well. There are two covered screw slots in the bottom of the case, so one could slide a cased Pi into place mounting it on a fixed surface. Since opening the case is done by springing the sides and prying the bottom off, you're not going to be able open a case that is mounted.
The bottom of the case has small raised, hollow circular sections for feet and is supplied with soft plastic hemispherical plastic feet with adhesive backing that fit inside the raised areas, making very good anti-slip feet.
There is a tube molded into the top piece of the case so you can look into it to see the LED indicators. There is no access provided for the GPIO pins. No doubt a short session with a Dremel tool would remedy that if it was an issue.

All in all...a very nice case design.
