The two hinged side doors make working inside the Z-Machine much easier than its predecessor, the Fatal1ty FC-ZE1. As you can see in the photo above, the large left side door opens all the way, allowing the door to rest on the table top. This prevents straining the hinges and for the most part gets the doors out of the way.
I installed a full size Asus P5N32-SLI Deluxe motherboard into the chassis without issues. The Z-Machine enclosure uses threaded standoffs for mounting points and everything lined up and fit perfectly.

Both of my double-wide video cards slipped right into place as did the sound card.
