The mount for the motherboard was made out of 1/4 inch plywood that I cut a section out of to allow the monitor ribbon connection through. After a bit of work I was able to get exactly the right thickness. I ended up buying a thicker piece and through a process of squashing it with a rolling pin and heating it in the oven. The only sizes I could find were either to thick or thin. Finding the correct foam to was actually a bit of a problem. Then I used double sided tape to hold the circuit board in the correct location. To do this I cut another layer of foam for it to rest on the edge of the frame without pushing on the screen. Also there is a skinny circuit board that provides high voltage power to the back light that sticks up about 3/8 of an inch that I needed to take into account. (since there is no longer any glass) Once the screen fitted correctly, I had to figure out a way to put the electronics on top safely without putting pressure on the back of the LCD. This turned out to work really well and was stiff enough to hold the screen in place without any worries that it will move or fall out. Step 2: DissasemblyĪfter looking at many other peoples projects I decided to use foam to mat the monitor and use foil tape to hold it in place. Since I don't plan on having an active cooling system every bit of power savings equals less heat to have to worry about. It allowed me to manually under clock the CPU from 650 MHz to 500 MHz and reducing the CPU power usage from 9 Watts to just over 5 Watts. While this might not sound like that big of a deal especially since almost every laptop now has this technology. Pentium III 650MHz 440BX cheapest motherboard 128MB PC100 SDRAM 15" 1400x1050 LCD ATI Rage Mobility 128 w/8MB SGRAM 20GB 4200rpm hard drive 8x/24x DVD/CDROM drive Integrated floppy drive A major bonus about his laptop was that is was the first Pentium III that used Intel SpeedStep. The only issues were it has the 1440x1050 resolution monitor instead of the rarer 1600x1200 option and it would flicker lightly especially when looking at the color blue. That's like a savings of $3,726 in only 8 years. After scouring cragislist I found the perfect system for only $50. Much of that cost came from the impressive 15" screen. At $3,776 MSRP this laptop didn't come cheap. After doing some looking online I settled on a Dell Inspiron 5000. On one hand you want the slowest, least power hungry system while wanting the highest quality screen. Trying to find a good laptop for this project was a bit of a stretch.
