TechPowerUp published a review on the Azza Legionaire
A quote from the article:
The Azza Legionaire sports a unique metal mesh side panel all while offering an E-ATX capable interior and the usual features of an ARGB controller, four fans and plenty of radiator support. With such a side panel, thermals are certainly something we will look at to see if a mid-tower can benefit from the same access to cool exterior air as small form factor enclosures.Azza Legionaire Review
