it is a very tight case. Having sized up other CPS1 PCBS in it, it wont even fit any of the C-boards with kick connectors or components on the topside that stick up further than the battery.
Assuming that the multi simply fits in place of the B-board and you're using an appropriately sized C-board I don't see why the multi shouldn't fit in one of these cases though.
