This is a very nice piece of packaging. Although the Amazon product description doesn't say so, if you've done your research you'll know this is a barebones system, not just a case. It needs to be: to package a well specified i7 system into such a small case, the cooling system is very carefully designed, which means the system comes with a pre-installed motherboard and cooler. Everything is well laid out, and the construction of the drive cage is very thoughtful. Documentation is also very good and very clear, with many clear colour pictures showing you step by step how to assemble a system.
I have fitted mine with a DVD R/W drive, a two terrabyte hard drive, a 64Gb SSD, a double width video card and 16Gb out of a possible 32Gb of RAM. It all went together very easily indeed.
