It and the 610 both came in the “pizza box” form factor, while the more expandable Centris 650 lived in a recycled Macintosh IIvx case which was both taller and deeper. All three models came with System 7.1, and could run up to Mac OS 8.1 which shipped in early 1998.
Now that we’ve looked at the

why. By this time, the LC line was anchoring the low end of the Mac product line, and the Performa was still mostly just rebadged LCs and Classic IIs. On the high end of things, the Macintosh II line had faded away, and Apple was replacing it with the 68040-powered Quadras. These machines were much more capable than the 68030-powered Macintosh II, and as the tech moved on, Apple put the 030 in service across the LC line.
