I'd agree, since going to 140mm fans I love them. Not sure about the panel window, if it's really much smaller or just an odd angle in the photo. It's not as bad as some cases that only give a tiny peep hole along the top for a window. I like the larger windows too, a little framing around the edges is nice for obscuring lighting and preventing direct glare from led strips. Just have to give a little effort to cable management with a larger window though newer cases are making it much, much easier.
Outside of going to the trouble of custom sleeving cables which can be a time suck it doesn't take near the effort it used to. Back when there was no room behind the motherboard, no slick grommets to pass cables through at various points and back when we had to use wide ide ribbon cables or scsi cables. I don't know why more cases don't at least give a dual mount option with holes for 140 or 120 at the rear/front. 140's aren't that much larger so the case shouldn't have to be made that much wider.
The top of the case is kind of a nice style touch with the semi floating 'panel' and soft blue lighting separating it from the rest of the case. Makes it stand out a little more from other similar cases.
