My New Quadra 800

[jmacz]

The Quadra 800 is finally finished. USPS / UPS Mail Innovations lost the Fujitsu 640MB MO Drive I bought on eBay (from China). Finally got a refund and then purchased a Fujitsu 2.3GB MO Drive (my second one) instead of a 640MB.

Finished modeling the Quadra 800 bezel for the MO drive. It could use some more work but I've got too many projects backed up so decided to just go with what I have for now and revisit it sometime in the future for a perfect fit.

The current model:





My resin printer isn't large enough to print it in one piece so had to split it into two pieces and join it together after printing. Here's post printing:





I also had to make a new mounting bracket for the drive. I needed to lift it about 1cm above the sliding mounting plate that comes with the Quadra 800 for that drive bay.



And here's the final shot with it installed. It's the last bezel with the blue MO disk sticking out.



Was debugging my first 2.3GB MO Drive with @olePigeon and it looks like that one has some issues. This second 2.3GB MO Drive is working great. CDROM drive is also working great.

Oh, a shot of some of the prototype bezels (via 3d filament printing)..

Noctua NF-A12x25

• Pressure: 2.34mm H2O

Haven't seen it explicitly mentioned here, but static pressure is also very important for fans like these. It has to pull air through the entire system, so it deals with a lot of resistance. This makes static pressure incredibly important, and generally higher static pressure results in more noise. Quiet fans are nice, but they're designed with modern PC cases in mind, which generally put a lot of emphasis on airflow, making it easy to push a decent amount of air around with low static pressure. Which is not the same with these old PC and Mac cases, where generally a single fan located in the power supply had to pull air through restrictive spaces.

Thanks @Daniël! Yeah, I left the stock fan in there for now.

Wow, that's a great result -- out of curiosity, how does a resin print replicate (if at all) the texture of the original plastic?

It depends on the model. My model is smooth so the end result is also smooth. I am sure you could find a way to texturize it but I did not bother. You could also update the model to have the texture I guess.
