The model showed 180, but the part was 3/280s-8r1, with all the upgrades! The actual hardware was dead - but it had all the panels and covers for the rack including the SCSI access. The original 180 chassis has housed everything from a pentium 90 to a 32-core threadripper. A fun bit of history. Hanging a mini-itx board in there was a bit comical for a few years, when folks were asking to see what was inside that monster.
