I will have some updates closer to the end of the week
I am waiting on your updates.
I need a switch, but need a cover for it, before I invest in the S3+ :-)
( I actually assume the switch will work with S3+ )
It will work with a standard ATX PSU that you would use to power a S3, yes. That said, the group buy is closed and we're not shipping additional units. Someone may be able to hook you up here, however, as a number of people ordered numerous units!
Cheers.
