Build Success

Of course, but what i mean is basically:
More power to understand more complex mechanisms

What? I doubt there is anything important not understood about the ps3, and even if there was, how would access to a fast computer help?

8RISC CPU (8mb each) / 64gb RAM / 6 x72gb FC disks is certainly more powerful than modern PC

This is all useless for all practical intents and purposes.

Imagine a (really) powerful host , an attached usb to sata adapter with a ps3 sata hdd .
wouldn't it be useful for some purposes ?

No, not at all. Technically slower than a normal SATA SSD too, not that disc I/O is important anyway.
