Hey all, Worked on this cube mod Summer of 2014. Still in progress and 90% done but wanted to share what I have and the steps I took to get there.


Inspired by thegyufi's G4 cube mod. I tackled it looking to make a replica but with a personal spin. I speak a good amount of French so following his log was fun and informational.




Got it in and it's in great condition! Stock 450mhz model. Non-working. There was some stress fractures in the polycarbonate case which I address here


Pictured next to my G4 tower hackintosh (will post in the future ;))

Case Disassemble & Heatsink cut:
Pretty standard across these mods.

Took the sides to a belt sander to get a nice even brushed look. Clear coated to prevent oxidation

ITX Tray:
2015-02-20 17.16.16.jpg
Cut the ITX tray from a really tough and thick slab of stainless steel I got for free. I couldn't find a template for the ITX layout absolutely anywhere. So, I did my best to make my own using my mobo. Only issue...it doesn't lie perfectly flat.

I botched two of the holes. I tried using a metal epoxy to fill then redrill a new hole but this didn't work because of how tough the metal was to work with. Any new hole slipped back to the original hole.

So I cut another one and that was a success


Fitting Motherboard and Pico PSU:

I had to take a different approach than thegyufi for this. My motherboard simply had a different orientation and it wouldn't work with his method.

Using my template on a nice thin sheet of aluminum....clipboard

Used a 4.5" (114mm) holesaw. Spot on!

Dual 2.5" HDD mount:
IMG_1732_1024.jpgIMG_1809_1024.jpgIMG_1811_1024.jpg
Used some aluminum rails and a VRM heatsink to make a sandwich with a 2.5" HDD and an SSD. Used epoxy to attach it to the backside of the itx mount

Test Fit:

Fitting with blu-ray drive, Mobo, and hdds. At this point, the shell and top plate has been cut

Filling holes with epoxy putty

Outer Polycarbonate Shell:
IMG_1758_1024.jpgIMG_1757_1024.jpgIMG_1756_1024.jpgStress testing I found that the CPU would still get fairly hot and decided to cut a hole in the outer case as well. Breathes easy now :p

IMG_1737_1024.jpgIMG_1739_1024.jpg
Using images from thegyufi I carefully drew out the design. I considered changing a few things or trying this approach with a different style. in the end. I cut it out keeping his design I liked it so much. Used a jig saw for this cut. Tried 4-5 different types of blades, ended up using a quick cut wood blade.

Removed the apple logo with rubbing alcohol and a spudger. Rough filed cut can be seen under wired vandal switch and top opening.

sleeved 24 pin connection and fitted into case. If you havn't guessed, going for an orange theme here

Pictured next to his unmodified and fully functional brother. Has a frosted glass effect from preliminary sanding

How it sits today as a HTPC Hackintosh

Still needs that final paint job. I've been both putting it off and waiting to tackle this final step. I want to get everything 100% before I paint it. Also, sanding this is going to take some serious time to get a blemish-free surface.

Inspiration for the final paint color:

A pearl white like my iPhone case.

Screen Shot 2015-11-29 at 20.29.28.png

System Components:

Idles temps: 30-32C
Load temps: 70-76C - Prime95 Small FFTs. Definitely passes the Intel recommended [SUP]T[/SUP]CASE of 71.35C. I won't ever push the system to this temp through normal operation. But it is nice to know where things settle at.

Hackintosh Installation:
Followed this guide by Stork and it works wonderfully
Only hiccups:
  • When ejecting a disk to put in another, drive won't load second disk until restart.
  • I never put it to sleep but sometimes when the screen wakes from being off there's no video output. I have to force restart which brings down my whole WiFi network which can only be remedied with a router reboot. Weird.
    • Planning on switching over to Clover, hope this will fix it

Benchmarks:

Oh my god you did an amazing job on this cube!

I see where you get your inspiration from :D (the french blue&white cube)

Do you have plans on painting the outer case?

Rick,

Thanks!

I sure do! Check out the end of post #5. Shooting for a pearl white finish using RC car paint Duratrax from a hobby store. It's specifically formulated for Polycarbonate. The outer case needs quite a bit of sanding prep though. At this point I kinda regret taking a mouse sander to it because it's going to be more work getting the 'spirals' the low grit sanding paper put into it
