Up-thread, Antarius says he transported a PC with him (presumably as carry-on). I'd say he was somewhat lucky and/or had the ability to re-seat the cards and what-not that easily shake loose.

I am not picking on OP nor defending AA, but it is a bad idea to transport a PC no matter how well it is externally protected. Here's why: Inside the box there are a multitude of internal cable and socketed cards that can shake loose from even minor rattling around, such as being gently transported in a car trunk or back seat. It is not hard to imagine the gorillas (baggage handlers) literally tossing a well-wrapped case onto a luggage belt or into a hold.

This is going to sound snooty. There are precious few PC assemblers who are competent enough to secure the internal components for delivery to a retail store or to a home for the retail mass-market. I've assembled PC's for my households' use since home PC's were invented. It's a skill just like car re-building or being a mechanic. Most people are not going to learn it because most people have better things to do. This is my personal opinion and take-away: Do not buy a PC (aka a windows box) unless you have the skill to assemble it from components. All others, just get a laptop, gaming device, or anything made by Apple.
