you saw 1 video or 10 saying that about cable management?
1 video is rarely the definitive answer to something. watch more and see what they say. if you get 10 that say it sucks, then i'd believe it. but 1 is not enough to base a decision on.
A couple have said it. The PSU isn’t fully shrouded, so the cables come into view, plus a lack of cut outs, mean cables have to be run further in view.
