thank you all very much :P
And yes .. for me it is also more a piece of art, than a computer

I tried to make an overview of the costs.
This moment, I have spent about €160 on materials (excl working tools), materials like, clear plexi / wood MDF / aluminum sheet / glue / screws / bolts / paint
I started working on Elements of Fortune in december 08, so the costs/month are approximately € 22

I hope to get some sponsors that see potential in this project
Until now, I have 1 sponsor - a computerstore here in my village (Autosoft)
He will have the privilege to show this case in his computer store

Maybe I'll update this evening or in the following days
Greetings
