The LC 580 is essentially a lower cost version of the Macintosh LC 575 as the system uses a cheaper CRT and IDE instead of SCSI. The 580 is the last of the all-in-one LC models based on the 68k platform (the Power Macintosh 5200 is sometimes referenced with "LC" at the end).
Due to design changes, the LC 580 board cannot be used inside the Macintosh Color Classic.
