The big holes are just for cable management (the latest rev. of TJ07 doesn't even have them).

I marked the mounting holes that are needed for the HR-01 X, fairly easy to spot whether a case has them or not (basically 2 rectangles). The TJ07 can take eATX boards, but standard ATX + these mountings will be enough for the Z7S. I just don't know if there are any standard ATX cases featuring these mountings..



You can always take any case you like and modify the tray to fit
