UPDATE TIME AGAIN: i was lamenting the fact that I broke off one of the mounting "snaps" on the backplane cover I'd intended to use for the hack, but found gold while digging through the
Magic Plastic Shoe Boxen for a replacement.
I found the (probably from a 6400) two slot backplane that came with my 6500 board! I'd forgotten that I ever had it! This will make me re-think a few of the graft points and actual connections, but it's already well on its way.
Whatever! Here are the new pics:
Here's an overview of the new stuff and progress on the hack to this point.

Here's one showing placement testing of the PSU. I did a Graphite Stick rubbing of my ATX PSU of choice at the store, copied the filthy thing and taped up a fairly good mock-up for working out its suitability. It's lookin' really good so far, first thing I'll do after buying it, will be to take it out of its case and either mount it to the existing standoffs (not too likely) for the ZFP HDD's PSU or else drill the suckers out and use create new standoffs with flat head bolts ( so the assembly will still slide in and out like a charm ) through the bottom of the internal ZFP chassis, right where I want 'em.

This shot shows the choices I'll be sorting thru to make the backplane look as stock as possible, make the top (Video Card) slot's Backplane Bracket and monitor connector(s) visible and accessible, You can see where I've already lopped off the bottom of the plastic cover in order to match the bottom edge of the Classic's shell. I'd like to retain a thin strip of the 6 mm plexi "spacer" , all the while making provision for some custom galvanized sheet metal work to induce proper airflow patterns as well as RFI Shielding between CPU and PSU.
Me like sheet metal challenges! :rambo:
Muahahahahahahahahaaaaaaaaaaaaaaaaaaaaa! }

This shot shows just how close a margin there is for doing the
Compact Mac Shortbed Takky Hack!
.
.
.
. . . and here's a closeup, notice the contorted bending necessary to retain the original equipment Medusa Cable Harness mounting slots. If I were to do this hack without the
Cellar Expansion Bay, I'd make sure to shore up those heavily rework hardened slot arms so the 6360/6500/1 slot riser MoBo could be slid in-n-out with impunity. Taking the MoBo out of my hack will be a little more involved, but I'll have access to the brackets to brace them with the 'ole pinkies! [

Here's a shot of some of the new "Optical Bench" paraphernalia, I picked up a second, as is, OHP for $9 that works fine with the lamp in the socket and there's a spare to boot! So, of course I tore the head completely apart for experimentation, first with a flat etched glass rear projection setup, and later, using a sandblasted, vacuum formed plexi, ersatz CRT. I won't be doing that within the confines of the Mac shell, but I WILL set up said confines for the "Optical Bench" experimentation sessions.
Once I have the optical setup dialed in for flat surface rear projection, I'll do my vacuum forming experimentation and play around with achieving the perfect
curvature of field of focus and
pincushion distortion to achieve a rectangular, IN FOCUS, properly sized rear projection image . . .
. . . or I'll take the lazy way out and use flat etched glass plate rear projection with a clear plexi CRT face stand-in. }
Whatever gets the best results wins . . . I'm
not ALL THAT MUCH of a purist! [
