Needed a build for overseas travelling, RVZ01B case was about the slimmest I could find, though still too big for carry-on really (unless you carry it by itself).
The RVZ01B was kind of a PITA to work in, as I expected. OS was the biggest hurdle overall, the EZ tool was useless and unable to successfully format any USB flash drive I threw at it to circumvent the USB 3.0/DVD issue. so I ended up having to get windows 10 instead of Windows 7 (which I detest, but didn't have a lot of time).
The RAM I had laying around, so that didn't cost me anything.
Does what it's supposed to, no more, no less.
Keeps the CPU well cooled, little noise.
Lots of Z features for less, good quality.
Runs pretty hot.
Solid case, wish it was a hair smaller.
