I asked Fatih, as he is the one handling all this.
Just shortly before the cases should be taken on board, we started looking for a second board company in case the current one don't do their work properly.
As the new company is in Taiwan and also offers assembly of the units, he didn't ship the cases, as we weren't sure whether we'll assemble all of the units in UK or parts already in Taiwan to speed things up.
I didn't know this and as Fatih doesn't read the boards here too often (you barely can see him posting), there was a wrong information, sorry about that.
I also thought they are on their way
