It won't damage anything if you get the front panel wrong, it just won't start, i've done it a few times, every board is a little different and it can be maddening, the power and reset don't even matter which way they go, but even with the one's that do, it won't hurt anything if you get them backwards at first.
the thread won't close if you pick a solution, but it will be marked as 'solved' which makes people much less likely to come to your thread. If you post to the thread after that though, other people who have posted to it will still get a notification (myself and InvalidError)
