I guess the 750D airflow edition has a thicker front door than the standard 750D. I don't know, I only have the 750D airflow edition to check it with. But if you get this you'll have to leave off the front door because you won't be able to shut the door enough for the 2 latches on top to connect. Even if you don't use the stick on bottom magnets from this non ferrous model, it's still too thick to close and latch the door. It's either leave the door off or sanding down the inside of the door about 1 CM. I think I'm just going to leave my door off since the DEMC filter is so much better than Corsair's. But it still deserves 5 stars because it's such a tightly woven mesh. The only thing getting through it is air. lol Or water I suppose, but then you have much bigger worries than dust. :)
