CPU and GPU still dump heat in the same chamber, so it’s probably not gonna do anything special.

Fatter, dual chamber cases, with the PSU and drive cages behind the motherboard already have proper bottom intake, that’s not blocked by anything like the PSU (shroud), so this case is not doing anything new.

As long as the gap between the two chambers is big enough, so air isn’t hindered, it’s probably gonna be fine, but mostly a gimmick.

From the article:

While it was never a mere recreation, it expanded significantly over time. Nowadays, Turtle WoW differs from World of Warcraft with features like additional playable races, leveling zones, quests, endgame content, and transmogrification.

I think around the time Blizzard did their Season of Discovery for Classic WoW, I heard a lot of people talk about Turtle WoW and how they want something more like that (Classic+) and not just the old game anymore.
