As long as we’re spitballin’ here…
With all the intended internal bits collected in a pile:
Think I’d probably build an initial, mock-up case out of 1/8” masonite (wood fibreboard) and wood (internal framework) first - just to get everything inside before… later, possibly fabricating an aluminum case for it all.
(Too much greasy, dirty mechanic work ‘round here lately and I’d really like to get back to making some sawdust!)
AND why not two internal PSU’s? One for the MOBO and all the original 450 MHz G4 “stuff” and a smaller AT(X) PSU (5 volts & 12 volts, right?) to independently power all those HD’s and their necessary fan(s). All packed neatly inside the mock-up.
Two “On” switches… HD’s and fans first, then the MOBO.
Masonite is so easy to work with… you can score and cut it with a razor knife and it drills so easy. A friend of mine built several 20” x 24” (and smaller) commercial graphics cameras almost completely out of masonite. And with an internal, wooden skeleton framework… all outer panels can be removed and replaced as the build progresses to allow for any changes in the internal layout for fan venting, design changes, etc..
Push comes to shove… one could always coat the final masonite case with truck bed liner and simply call it the “Dark Tower” or “Ahab”.
Sorry Nano, you sought an existing case. (Google, tons available 4-ever.)
*From a brief search today, looks like Marathon was around up until 2001 or so before being acquired and then… ceasing production of those PowerRack G Series cases. Now unobtainium / hen’s teeth.
AND IIO, again… how many VGA cables do you need? And would they be VGA / VGA or VGA / DVI? Fairly plentiful around here, $20 and under. Does it have to be 4 meters long exactly? I’ve a 20 foot Belden VGA / VGA I’m not using - but probably cost more to send it to you than you could find it priced locally?
