Beautiful!! But I still prefer it original desktop case, personally. So in the end I will spend whatever it takes, expand it to the maximum capacity that I can expand it in a desktop case...and enjoy it this way. No other way for me 
Yes - I also like classic A1200 case. more than tower. Its more "Amiga" way than towers. Original A1200 case is very attractive - design is beyond its time and even today a very attractive case.
But the reason I done this midi-tower solution is to have proper PSU, cooling and space for hard drives and DVD.
The combination of BlizzardPPC + BVision is very hot and I had problems in stability of the whole system. Before I was using PPC only occasionaly, but when I started AmigaOS 4.1 that is working 100% on PPC it turned out that system is overheated and unstable.
Now I have temperature of about 33 celsius in midi tower (outside the tower temperature is 25 celsius). When I remove that big fan that is located in the front of BlizzardPPC/Vision the temperature is also very hot!
I dont know if other people have the same problem in original A1200 case?
