The Apple Macintosh Quadra 950 features a 33 MHz 68040 processor, 8 MB or 16 MB of RAM, and either no hard drive (just a 1.44 MB floppy disk drive) or a floppy disk and a 230 MB, 400 MB or 1.0 GB hard drive in the same gigantic tower case design as the Quadra 900 before it.

Just like the Quadra 900, the Quadra 950 offers numerous expansion options -- sixteen RAM slots, three drive bays, and five NuBus slots.

In the picture, the Quadra 900 is on the left and the Quadra 700 is on the right.
