From early 2002? This PC-7 is a more budget friendly case that specifically drops the removable motherboard tray of the PC-60. It's otherwise very similar, and much like the PC-60 USB includes 4 USB ports behind the front door, and I believe that makes this a PC-7 USB. The front grill was a devisive design and not always liked, but I like that it's unique in this bunch.
