Background: a friend of mine gave me a laptop for free. It had a totally broken case (hinges and all) and a dead battery. So i said... what is this useful for? A desktop, of course.
PS. This would look great wall mounted. It can also be made into a tablet (although rather heavy) by adding a commonly available touchscreen kit.
PSS. I'll add more pictures this week.
Step 1Materials and tools
To accomplish the mod, you will need several materials and tools. The materials are:
-Enough acrylic to cut three scree-sized panels (varies on laptop size and craftsmanship--read below)
-Four screws at least the size of the expected thickness (depending on laptop, see next steps)
-Eight nuts for the above screws; four of them normal and the other four locknuts.
-Enough screws to secure the motherboard; depends on laptop.
-Spacers (the screws used to secure the motherboard must fit in the, the size depends on the motherboard. -A pushbutton (the new on-off switch)
-About three feet of wire.
-The most important material: a laptop.
Tools
-A drill
-A hacksaw
-Screwdriver
-Soldering Iron
-Elbow grease
Step 2Dissasembly
Disassemble the laptop. Each laptop is different, so I cannot provide specific details. From my experience, there is almost always a screw under the keyboard that prevents you from separating both halves. At the end, you want to end with the screen, the motherboard, and things such as the hard drive and the ram. The touchpad, keyboard, and webcam will not be installed, these will be external. (Common USB keyboard)
Step 3Front face
Measure the screen and cut an acrylic pane larger than the screen's border. The exact amount you must leave to each side depends solely on your craftsmanship. The better you are, the less margin you will need. (Bear in mind that there must be a margin in both sides, so the final size would be the screen size plus two times the margin)
If you are like me (aka bad), leave a wide margin, around an inch to each side of the screen. This gives you a large margin in case you need to drill something again. This large sheet will be the front cover.
Then, cut some strips such that they overlap the bigger cover on the margin. This means that if you left a 1 inch border, you must cut four 1-inch thick strips and place them along the corner. The void in the center is the place where the screen will be, the strips will maintain the screen centered.
Drill four holes, one in each corner of the cover and their corresponding strip, and insert the 4 main screws. Do not insert any nut in these screws yet.
Step 4Middle cover
Cut another acrylic sheet, the same size as the one that corresponds to the main cover (which is the screen size + your selected margin) drill four holes at the exact same location and make sure the screws go through.
Make a slot for the screen's cable. to do this, drill four consecutive holes using the drill, and then file out the irregularities. Insert this cover on top of the screen, which should aready be residing in the front cover between the strips.
This is similar to a sandwich. At this point, you can insert the normal nuts into the screws.
Step 5Back plate
Now, we are going to make the back cover. First, cut an acrylic plate the same size as the front cover and middle cover. Drill the same four holes you have done with the previous layers. Then, place the motherboard over the middle cover in a way you can connect the video cable to the motherboard; the side that faced up in the original laptop (keyboard side) will most likely be facing down, towards the screen. Connect the cable from the screen to the motherboard and position the motherboard in a way such that the connectors (USB, ethernet, etc) just at the border of the sides of the acrylic.
Then, position the backplate over the motherboard and mark in the acrylic the positions where the motherboard screw holes are. Take off the back cover and drill the holes. Then, reposition the plate over the motherboard and insert the screw.
There are many screw holes in the motherboard, but if you have a bad craftmanship, you can have the consolation that you only need to line up three holes (of the eight or more that the motherboard has). Use the spacers to keep the motherboard level with the middle acrylic layer. The spacers must be present both below and above the motherboard Use the smallest spacers that can be used while still keeping everything level.
Step 6Fan holes
First, print a fan hole template. I used this one , resize it to your laptop's fan size. In my case, the fan was 4cm tall and 4cm wide.
Place the pattern over the fan and place lots of transparent tape over it, so that when you drill through it, the pattern does not move.
Now, remove the backplate from the rest of the assembly, place it on bench and drill the fan holes with the largest bit that you can comfortably use without risking breaking the pattern and/or the acrylic.
Step 7Power button
Most likely, you will have to relocate the power button. To do this, first determine where the power button was originally located. Then, solder a pair of wires to this button.
After this, solder the other ends of the same wire into the pushbutton that will act as a replacement, and then stick it through a hole drilled in the acrylic. The exact dimensions of the hole will varie on the button you choose to employ in your laptop (or desktop, as you want to look at it.
Step 8Finish
Put all the acrylic and computer pieces together in their respective order. The top layer must be between a normal nut and a locknut . This applies only the screws at the four corners. I know my explanation is a bit unclear, but a picture is worth a thousand words.
Now you have a nice desktop (or tablet with a touchscreen kit), sit back and enjoy.
