My interest in both woodworking and PCs have encouraged me to make a wooden PC case.
There was a lot of thinking, measuring, drawing ...and there was Internet for the ideas.
Eventually, I got started without any complete plan and now my project is stabbing down more than 100 working hours.

Step 1: Routing the Connections

Step 2: The Back Panel

Step 3: Mounting the Motherboard

Step 4: Graphics Card, Wifi Card and Power Supply

Step 5: The Fans and the Buttons on the Front

Step 6: Harddrive Tray

Step 7: Making a Window in the Side

Step 8: Painting the Whole Construction and Mount It Together

Step 9: And This Is the Result

I also mention the technical content here, but this was not my priority,
for me making the case was the most important.

Motherboard: Asus P7P55D LE
CPU: i5 750 2,67Ghz
Memory: Corsair Vengeance 2x4GB
Graphics card: MSI GeForce GTX 750 Ti
Power Supply: Cooler Master G650M
Water Cooling: Corsair H60
SSD: 120GB Samsung Evo 850
HDD: 2x Samsung 3.5 “2TB

Furthermore there are two Noctua fans inside, one fan from Cooler Master, and a laptop DVD writer from HP.
The fan grills, the legs and the front USB ports come from old desktops.
The system is installed with Windows 7 x64.
