Step 1 Power Supply

• First things first : you'll need a reasonably dead Mac Cube power supply

Step 2




• The first step is to separate these two end-caps
• Each of them has 2 very strong (and equally brittle) clips holding it in place

Step 3
• The only way to access these clips is through the ventilation holes, .. how convenient !
• It's enough to unhook 1 clip per side, and one of the clips cannot be unhooked, as it's blocked by some black paper plastic rubber thingy
• It is highly recommended you go in through the marked holes (those are the largest open areas inside the PSU anyway)
• In case you have something thin and strong enough to do this without enlarging the holes: please leave a comment down below !
• I drilled through the existing holes to make them large enough for a fittingly stiff screw driver
• BEWARE : this plastic is incredibly brittle and will crack very easily; using a stepped drill bit for the plastic, then a regular bit for the metal worked best

Step 4
• Once you've enlarged your holes, it's just a matter of carefully prising these clips free
• Again, be careful, they're very brittle
• Since peeping through a 3mm hole doesn't give one the best visibility, here's also a photo of the power supply board, so you know what to look out for ;)

Step 5
• Correctly assuming you've gotten rid of all the plastic surrounding the metal chassis, it's high time to open a bottle of something !
• Unclip metallic end-caps with a relatively skinny flat-head screw driver

Step 6
• Now, the last step is to unhook the two halves of the metal chassis from each other - with the correct motion, this happens very easily
• Firmly press on the top half (the bottom has the PCB laying right against it) whilst prising with a flat-head screw driver at the seam: there's 3 metal clips to unhook on each side
• And you're done !
• Feel free to share what problem yours had and how you've fixed it down in the comments :)
