Actually considered going that way, Also thought about going the direction of the innovation from the folks who do the much simplified IIsi/LC verson of a PicoATX PSU, forget the name offhand.
Not fully wedded to flatplating an available PSU component below the mezzanine level though I'd like that.
By doing an SE/30 form factor board for the Classics (with the rest of the Compacts as well) I think I'm meaning something different than the words I've managed to string together so far. The thing I'm beginning to love abolut the Classic is that in no way shape of form is its Power/Cooling budget achieved anything like its forbears!
What I'm visualizing as an SE/30
style makeover of the Classic II A/B:
1 - clear the lining of that full metal jacket (nice 'nic) of all but video circuitry/flyback and harness/power connectors as required.
2 - adequate PCB silicon forest is clear cut to bolt a high output, Seasonic style SE/30 PSU replacement right up to the new A/B PCB?
3 - implement self-discharge bleed to everything attached, so no metal can requirement for PSU or poking around under the cap?
That ducted fan setup buried on in the Classic chassis is looking quite elegant the more I look at it from every angle in the pics I've harvested. It may be the only adequate cooling setup ever implemented on a Compact Macintosh, and no again, the CC is NOT Compact!
The engineers look to me to have pulled off the quietest, most efficient method possible for directing airflow across the components most in need of it? Are they really lined up like that? Burying the muffin and using the hot stuff like baffles in a muffler can't possibly push SE/SE/30 level decibel output through that nice big grill on the back of the bucket? Still couldn't get active cooling like that past SJ, but he was insane in the Pirate Period. Did the gang with the knowhow finally pull it off or what?
edit: thinking along the lines of a parallel Hybrid A/B Development topic. Thoughts?
