I realized I did not give your question a direct answer.
Its possible Lian-Li manufactures the case for Apple.
Apple does not own factories, almost everything they make is outsourced, exclusive of the engineering.
CPUS by Intel, motherboards by Asus, cases by...?
How many companies out there can MAKE high-end aluminum cases Not too many. Expensive capital equipment must be purchased to take aluminum sheet and process it. I give it a 75% chance that they roll out of Lian-Li's factory.
Here is a link to photo's of Lian-Li's factories:http://www.lian-li.com/about_facilities.htm
From Lian Li's Website, "Except for the above professional machinery, we create the necessary tools for our components in our own die room to speed up production time and lower the production cost for our clients.
What else could we need? "
I don't believe "clients" is referring to Newegg.
