I got this to put into a PotatoFI mini case. Unfortunately, I didn't realise it wasn't the right board for the case, and the header for the Pi Zero is on the wrong side, so you'll need to non-trivial amount of desoldering to put a header on the right side of the board.

Sorry to hear that you had issues with it. There are different styles available for different cases from PotatoFi. It sounds like you got the "Mini" case, which uses the "Compact" configuration of the RaSCSI. It is available as a configuration option. The version you got is compatible with the Slim and Pro cases.
There is a version that just has the surface mount components soldered, along with all of the parts you need to assemble it. Its available under a different Tindie listing, and is linked from the product description.
Please message me directly and we'll see if we can you up and going.
