The stars aligned, there was a great sale on HMKB cases, Promenade group-buy started and I found SA Recall for cheap.

Highlights

I really enjoy the broadwalk layout. The original broadwalk manufacturer closed down and I started working on my own PCB for this layout. Since I never did PCB design before it took a long time working on this on and off. After talking to Lord Boards about it he came up with a design called Promenade60. Things slowed down again, then I found a group-buy by Krado Industries called the Promenade. Luckily this one succeeded and I ended up buying two PCBs from them.
