So i acquired 3 Dell Optiplex GX400 (pretty obsolete) desktops, after stripping it down bare to salvage parts i din't know what to do with the cases. Initially I wanted to toss them out for recycling but i thought I might as well reuse/upcycle it into something better. At the same time my summer break was coming to an end and I had to pack up my tools to be transported back to collage where I stay away from home. So it struck me to put one and one together and build a toolbox out of the old PC case. Its portable enough for me to transport between collage and home, and can be packed up into a really compact formfactor for storage or transport.
Build time: approx 20-30 hours over a few days (i took my own sweet time )
- Dell Optiplex GX400 case at MYR 5(bought whole computer as scrap)
- Cardboard Calendar stand (free)
- Mounting board x2 MYR 4
- Mini Plastic Drawer x2 MYR 25 (entirely optional!)
- Some fairly stiff but form-able wires (had them laying around)
- Shoulder strap ( I got this free from an old bag rotting away )
- craft knife (xacto clone)
- Staple gun
With the vast variations of pc casings available over the years chances are yours will be quite different, in this instructable I hope to inspire you to breath new life into old "good for nothing" scraps and get organized at the same time. I hope that you would be able to get some tips (like the hook, it works really well) and ideas for your upcoming project.
Any constructive feedback is very welcome and if there is anything you wish to clarify, feel free to ask.
*your vote will be much appreciated too =)
Step 1: Power Supply Compartment
The first thing i did was to modify the plastic tab adjusting/controlling how much to open it by propping it up.
I cut the channels deeper to allow it to move more easily.
Next is to build the box, I am really sorry but somehow i cannot find the pictures showing the build process. But basically you just need to make a box that is the size of a desktop power supply and attach it to the case as if it was a power supply.
Step 2: CD/DVD Drive Compartments
The width and the height will be roughly the same as a DVD/CD drive and the length will be slightly more as it will allow us to use the space more effectively. Here I measured the length such that the box will go all the way in until it touches the "power supply" box
I made all three boxes out of mounting board, First you would want to cut the board to the right size with the dimensions of
Next draw the lines and score the lines at a distance of the height away from the 4 sides,
Then make a short cut from along the line until you reach where the lines intersect
(Please refer to the picture annotations for more detail/clarification)
You can now fold the tabs and staple it together to make the box
I attached mine to the original Drive holders with tape
Step 3: Hard Disk Drive Compartment
There is not much modification needed.
I just hammered out some obstructing metal tabs and used the scrap mounting board to cover up any big holes
Then i just added a "door" with a handle and viola!
I made the door slightly taller so it would be able to close both the main compartment and the slot for storing paper/sandpaper/fabric
Step 4: Additional Compartment 1
This allows the "power supply" box to act as the lid/door for the additional compartment.
It is a bit tricky as there is nothing holding it up initially and i had to add in wires to hold it
It is basically a cardboard rectangle held up by tape and wires.
Please look at the picture annotations for more detail.
However it is quite difficult to detail this process using words or pictures(apologize for poor pictures) and you would just have to go with whatever you can do depending on how the case is.
Step 5: Additional Compartment 2
The box is made such that it can only be accessed when the "Hard drive" box is swung out, similar to the first additional compartment where it utilizes a moving box as the lid/door
Step 6: Hooks and Mounts
The hook is basically a wire bent into 2 "S" shapes that are parallel to each other
remember to make one of the loops tight to ensure it fits securely on the fan grill
I also made a little horse-shoe-shaped wire that holds the staple gun to the floor of the case
Step 7: Mini Plastic Drawers
This is very straight forward, I measured how much volume I have as empty space and went out shopping for something that fits well
Step 8: Final Step
The strap is attached to the back at the padlock ring and I added some wires fixed to the front fan grill to attach the other end of the strap
Although the strap is attached to the bottom of the case at the front and back, it does not show any tendency to flip over as the straps are quite broad and grip the top of the casing
And thats all! we are done!
I hope if you are doing a similar project you would have as fun and fulfillment as I have
