I wouldn't call the AIO's unopenable. The 5xx series machines (LC 520, Performa 550, ect) and the updated version of this case design, the 5xxx series, could be opened in as much as a drawer could be pulled out, giving one access to the motherboard. Full openability would have been a safety hazard with the monitor tube built into the chassis.
This dichotomy exists to this day, and there never have been crossover products: the AIOs never have slots (or at least not standard ones)
While the AIO's didn't have
industry standard slots, the LC PDS slot appeared on many different models over the years, and third party developers created cards for them, making them rather standard on consumer AIO models.
and the modulars never include monitors.
The PowerMac 6200 was a 5200 in a Quadra 630-style case. The 6200 was sold only in Europe, but was released in the US as the Performas 6200CD, 6205CD, 6210CD, 6214CD, 6216CD, 6218CD, 6220CD, and 6230CD,
each bundled with a 15" monitor, and a different hard drive.

The G4 Cube came from the modular side - it was a repackaged Sawtooth.
Considering the Cube...
1) Used different sized graphics cards, on a
2) complete different motherboard that
3) had a power supply separate from the case which had
4) no similarities to the B&W G3/G4 tower case and
5) used slot loadng optical drives instead of standard tray-loaders and was
6) not really designed to be expandible, unlike the Sawtooth,
I think calling the Cube a repackaged Sawtooth is a gross oversimplification.

The only similarities are that they both had G4 processers (perhaps resulting in similar performance figures) and both used AGP busses for graphics cards.
