Just took delivery of the case… as its my first Rosewill case I don’t have anything to compare against to identify the differences, but I’m assuming you may be able to…
From what I have read up about it, I’m suspecting the main (noticeable) difference/s are to do with the front panel, which as a USB 3 port (I believe the older cases only had a USB 2 port?)
I also noted that the Mobo location appears to be a removable tray, but it would be pointless to remove the tray and mount the drive to it before installing the mobo in the case, as the mounting screws holes for the tray to the case would be underneath the mobo
Anyhow, here’s some pics of the case, freshly removed from the box, as I figure you might be able to spot any differences between the L4000 & L4500 from them. I’ll also note for the middle fan frame has a gap between it and case underneath it to freely run cables from the mobo to any of the drive bays in a direct line.
