I would seriously look at a different case.
The PC-50 has lots of "features" that are not in its favor:
1. It mounts the PSU AT-style over the top of the motherboard. The Z7000 may not even fit. And even if it does, it's going to make your airflow really congested up there.
2. It's really limited in terms of ventilation: 80mm intake, and an 80mm blowhole, which is not a nice thing for quiet PC's, it directs the sound out right towards you.
3. It's thin aluminum. Thin aluminum cases resonate, making an awful racket that hard to get rid of. Steel is generally preferred. (and ignore anyone who tries to tell you that Aluminum cases stay cooler, that's total BS)
For $80+, you can find much better options for cases.
Other than that, the list looks really good!
