This idea came up when I wanted to make a pc form old parts for my sister.I only had an old simple pc case but I wanted something a bit different that doesn't look bad to put in your living room.So I came up with this one..nice, blue cardboard box..

Step 1: PC Parts.

Please excuse my lack of step by step fotos,but I did this before I find out about this site so I only have it finished.I gathehered the pc parts,motherboard,ram,pcu,psu hard drives etc.
The most important here is that I took the metal pc case and dremeled it to pieces.The base were the motherboard screws and the pci-agp cards go is used as is because I wanted it to be solid enough and the cardboard was not.Also this way I have a better chance with the pci cards placed correctly.As seen in the picture in the left corner,its the dvd rack with the hdd rack uderneath and the psu on the bottom left.All of the components are bolded together apart from the duck tape you see.

Step 2: Cutting Holes.

What do we need next?holes..one for the dvd and some big ones at the back for psu and connections..I used duck tape around so that the cardboard would last longer and because this way it has a better finish.Also in the front,besides the dvd,there are the power on leds and the swich wich I used a small plastic dolphin just to fit the rest of the sea design of the case.

Step 3: Put Together.

Lastly I put put everything in and duck taped al the parts in the case.I don't know how long it will last but my sister loved it and I still works after 5-6 months..And of course wireless mouse and keyboard..
