Step 1: What you need and what you have
- i had a core2duo e6700, 4 gigs of ram, 2 old hdds, a mini atx motherboard and a power source (basically a computer)
- 2 buttons and two leds
- 1 quiet cpu cooler and 1 quiet fan for the power source (i bought the cheapest from arctic cooling)
Case frame: for the internal case frame i used some wood stripes i found in the basement but you probably could do better building an aluminium based frame.
Case cover: 3 old hard cover books, and one piece of plywood for the base of the case
Tip: always take in consideration when you measure your case that all the cords and cables take up some space, you should also check if some other components can be mounted after the case is finished. (ex: pci-e videocards or other pci cards)
