ginsu417 Posted June 30, 2020 Share Posted June 30, 2020 Hey all - I just finished up my second vintage Mac project. It's an 8-core Atom powered 48TB NAS inside a 1991 Mac Classic chassis. Full worklog here: https://photos.app.goo.gl/LfSziXHGaa3X4Cog8 Use a 40% hydrogen peroxide cream and sunlight to clear up yellowing caused by bromine contamination. Ready for science Test fitting an 8" 4:3 LCD display. Requires a custom bezel to fill gaps. 1 Link to comment Share on other sites More sharing options...
ginsu417 Posted June 30, 2020 Author Share Posted June 30, 2020 3D printing a custom bezel I designed in blender Seems to fit. I intentionally printed the prototype small just for fitment, so I wouldn't waste too much filament on trial and error. Then when I was satisfied with the fit, I went into blender, pushed the edges out and re-printed. Final Bezel design, fitted to the front fascia Display disassembled and fitted to the front fascia My assistant, Genji 3 Link to comment Share on other sites More sharing options...
ginsu417 Posted June 30, 2020 Author Share Posted June 30, 2020 New logic board - the Supermicro A2SDi-8C-HLN4F, and 32GB of RAM. 3D printed custom logic board mounts. These took about 4 tries to get the design right. I/O shield removal Dremel carnage New 3D-printed I/O shield. The display is inside, and Supermicro doesn't make a mini ITX board like this with an internal LVDS connector, so I have to route the VGA cable back in. It's not elegant, but it works. 1 Link to comment Share on other sites More sharing options...
ginsu417 Posted June 30, 2020 Author Share Posted June 30, 2020 Power. I wanted to retain the factory look from the outside, but no power supply has the switch and socket in the right place. So I needed to remove these pieces from the factory power board, and re-route them to my PS. I could have probably used a power cable with a 90 degree bend, but it was really tight and I didn't feel like tracking one down, so I modified the PS to pull the high voltage leads out and connect them to the factory rail. Black arrows are the spots I needed to unsolder to get the rail out it didn't give up easy and after I got all the small joints out, I just took a butane torch to the board and pried the rail off. That won't stop me. Rail fitted with new wires. PS modified with spade connectors for easy servicing 1 Link to comment Share on other sites More sharing options...
ginsu417 Posted June 30, 2020 Author Share Posted June 30, 2020 The logic board came with passive cooling, and I was seriously considering some crazy duct work to a case fan, but I ended up having tons of space above the CPU for a fan, so I converted it to active cooling. I didn't want to have to track down a cooler that would fit in the space, so I bought a ridiculously overpowered 60mm fan, and 3D printed my own clips to hold it down. The process was... let's say iterative. And at the last minute, I realized I'm an idiot and PLA has a glass transition temp of 60 degrees, so I re-printed the clips in ABS. 1 Link to comment Share on other sites More sharing options...
ginsu417 Posted June 30, 2020 Author Share Posted June 30, 2020 Display ran on 12v DC and gets power from the internal power supply. To make this happen, I needed to build a custom cable to plug into my psu. I sacrificed one of the molex cables from another project. LVDS mount location was later moved for clearance reasons. The 3D printed drive cage was going to be the heart of this build, since it secured the PS, all the drives, the case fans, and the LVDS board. It took 32 hours to print, but it came out pretty nice. I designed it to fit a cable management arm, and a fan plate to push air through the drive bays. With the two 92mm fans, clearance is tight. A cable arm will keep the SATA cables safe. 1 Link to comment Share on other sites More sharing options...
ginsu417 Posted June 30, 2020 Author Share Posted June 30, 2020 SATA cables with cable arm installed Cable routing 3D printed a plate that holds the 92mm noctua fans The print came out a bit stringy, and my choice of mounting hardware doesn't help. I'm not thrilled about how this looks and will probably redo it the next time I have the case open. Shot from the back of the new LVDS board location Some last minute testing before buttoning her up.
