99% of tower are maked by on manufacter and then adapted by other.
At home i have 2 peecees inside a "Power Tower" from power computing.
You paid too much becuase all amiga tower are tooooo expensive, this is bacause they must be adapted for amiga.
With amigaone won't be this problem again.
In all cases tower for PowerC and Elbox are good, in the past i bought a Infinitiv Tower (ALL PLASTIC) and it was more expensive than E/Box1200.
