Amazon just listed it wrong. It's a steel chassis.
Which is no problem. It's a great case.

I have been doing some research on the X99 motherboards and it's going to be hard to pick one.
I have found some sites stating that state problems with just about every brand including Asus.
I don't really put a lot of faith in NewEggs customer reviews.
I think I'm going to just wait until more reviews are done.
I would suggest holding off on the Sound Card until you get the system put together.
Some of the top of the line motherboards just might have as good of sound as sound card.
Take a look at KLipsch-THX/ 2.1 speakers. I have two sets and they are great for the money.
With that case and proper fans you should not need hard drive coolers.
You also problably won't need a usb 3.0 usb card with todays new motherboards. You could always add it later if needed.
I would also recommend taking a look at these fans.

Any Corsair AIO water cooler I have used I had to replace the fans because of noise.I replace them with Noctua fans.
Could you tell us how much money you intend to spend?
Could you also tell us what you intend to use this computer for?
