Cheers to you both have Looked into that but not very good write up Pixelmancer. Only wonder if Themraltake where going to look into it. That was basicly the Question. I like a case to have room with air to move and breath and Themraltake seem to be doing a great job of this. An as you said I am looking to build my own. Also Red Harbinger were looking promising with there desk as well, but seems to be hold up in getting there desk out in the world!
I thank ThemralMike for his reply.
Cheers
Richard
