Really well made. Super flexible and looks amazing on my desk. Well worth it if you are after a premium looking case.

Machining is nice... But compared to my original M1 v5 it seems like a half finished product... Having to pay extra for taller feet or for the non existant "to be released" front io header or fan brackets or rear panel covers for something in that price range is a bit rich.... Packaging was so and arrived damaged at least the panels were undamaged. PSU bracket mounting with just 2 screws from one side seems half-assed too.

Haven’t assembled as of yet but the machinery of the parts are very nice and high qaulity.
