The Stand-alone version could be of interest. But why not try to shrink the design down? The PCB could easily be reduced at least to half it's size. Most parts could be replaced with SMD counterparts (except for the LS-type logic IC's that are hard to find as SMD) and the PCB could be double sided. And that LCD should be hooked up with a piece of flat cable anyway to a suitable place at the case front.
