That's epic friend, big welcome on board! Of course, just send us an email with the color you want ?
Absolutely, send us an email and we'll figure it out ?
Hello friend, that will work absolutely fine! ?
A month is not going to be any problem, just let us know when you move and we'll update the address! ?
Sorry for the late response, I'll head on over to the DMs straight after this post ?
Probably, but I can't guarantee right now. However, if something breaks we'll most likely have spares in the factory. I don't really see how anything on MJOLNIR can break (except possibly electronics and glass if you smash it lol). So you let us know and we'll figure out how to send parts to you 
Good thing to note: anodizing is a very batch-sensitive process, so any anodized parts from different batches are not very likely to match perfectly. Best to get the panels you want now.
Huge welcome on board! ? Yeah get a couple 6-32 4mm standoffs and 1mm washers, that should do the trick. There will be some slight misalignment between the IO shield and the motherboard, but it's going to be within the "squeeze to get it in the right place" margin. Grinding down standard 6-32 1/4 inch standoffs to 5mm will also work.
I'm not super concerned about the M.2 drive, but the back plate for the CPU block is going to matter (i.e. it has to be within 5mm).
