Thanks for the warning about the batteries on the mobo's @Graham , I didn't even notice before you mentioned it, but looking again at the photos myself (the parts are once again boxed up until I can sort them) it looks like at least one battery has already started leaking on one of the boards and I'll have to get them cleaned up asap and repair any damage to traces there, if it's to late to clean them off and save them!
Thanks for the kind words @Andy Barr
