The mcgann is very hard to build because it is very detailed and its hard to find good images of it! below are good reference images I have found, if you know of anymore please add them. this will help people when they create mcgann interiors   like me

Comic Drawings

A lego version (not completely acurate but good nonetheless)

Here are 2 good videos aswell

A gmod version (not released yet or completely accurate but good also)

images didnt work, lemme fix them

Fixed

Not a bad thread a lot of people could use this but this is still missing a ton of detail

Well, I just found this site. 

Has some pretty darn great reference images for some of the Console rooms
