Amtrak finally arrived at 10:40. All the parts look pretty good, although there appear to be some missing blanking plates for the case, and a lack of screws to attach the motherboard to anything.
Just had a call from the suppliers, the blanking plates will be posted later, and I can probably find enough screws in my pile of spares. This evenings job is to build the machine up. Should be fun.
And finally, just for matt02: It’s now 8mm.
