About the case and MSI's MEG series:

If you're not familiar with MSI’s MEG (which stands for MSI Enthusiast Gaming) lineup, it’s essentially their flagship series, aimed at enthusiast builds and overall enjoyers of higher end options.

For the MEG MAESTRO 900R being given away here, here’s what MSI is highlighting: a centered internal layout, three-sided panoramic glass, and a detachable motherboard tray that can rotate into four different orientations. That gives builders quite a few options for how they want to assemble and display their system.

There are also some more premium finishing touches, including aluminum panels and diamond-cut detailing.

The four-way motherboard layout is probably the most interesting part from a builder’s perspective!
