Doepfer

Hi , 
I'm trying to build something like the A-100 G3 ( because they are not available anymore and need to fit the space) ,

Reading in the Doepfer web i found this: 
http://www.gie-tec.com/housings---profiles/19-inch-enclosures/index.html

there i found the alu frames and mounting rails and top + bottom sides.  Apart I'm buying the  Doepfer PSU2, back panel with switch and fuse holder,  and bus. 

Please let me know if someone has already built one like that before and if I'm doing well in getting those parts. Is it money wise convenient? 

Thanks

Ricardo
