There's cases that are easy to build in, have plenty of room for any kind of hardware, plenty of room for wiring, or any other mischief a beginner builder can get upto.
The case you chose is quite the opposite. It's a very specific case, with specific size hardware that fits, may need some slight modding or tailoring specific to builds etc. It's an advanced user case and that can create all kinds of headaches for ppl not expecting any hassle.
