Ok so i had a lenovo s10e, and it died on me, not the hardware but the case. it cracked and the screen came away from the main chassis. Also the fan made a horrible noise, it ran very hot and crashed sometimes due to the heat on the atom. I had the idea a long time ago for a small PC project (pre netbook days) but back then no components weren't available cheaply, and by the time they were, it was just cheaper to buy a netbook. So the project was forgotten.
But now i had the components and just needed a new case. I decided to make the new case capable of holding 12 cells, with the aim of getting a very long battery life with the help of good natural cooling. The original idea was to use an aluminium case and have the case it's self as the heat sink, by having the heat conducted away from the CPU via a block of aluminium attached to the base of the case. This idea had many pitfalls, mainly that the core might be damaged if the case was knocked or dropped. so i decided to make a new heatsink that should be capabler of passive cooling.
So after dismantling the netbook down to it's component parts, i started by making a mounting system for the board. The best way i discovered was a combination of support below, and at both sides. The board is mounted using the audio ports (which sit nicly in the holes drilled on the inside layer of the case) and on the other side likewise it is supported using the VGA port and the VGA screws hold the board very well.
holes to be made, for the board mounting.
needs filing down
a new base had to be made to give couple of extra mm depth in the base.
here it is mounted (very sturdy)
two motherboard mouting nutscrews are used in the VGA port mounting holes to secure the board.
