I have the 420. I got it on sale for $679. I wouldn’t pay full price for it.
It’s extremely solid, well-built and the power is great. But they use proprietary screws, although they’re available in multiple places. It’s quite difficult to screw in a thicker module while using washers. You’d have to measure and get longer screws and make sure you won’t bottom out the rail.
Other than that huge issue, it’s nice. Therefore I’m mixed on it overall. But I can’t complain lately because I managed to find some thinner washers that have worked and now my modules aren’t going anywhere.
Edit : unfortunately I can’t answer other questions or comparisons as it’s my first case. I decided to go prebuilt for sanity’s sake and it was the most HP for the money.
