I also have the Mirage4000 tower and was hoping to maximize the unit to be "The Power Amiga" in my collection but I'm a bit dissapointed in it. Though it's a sturdy, well made and ok looking the low amount of 5.25" places and weak PSU (aswell as the blue coloured details that doesn't do it for me) is a big downside in my point of view.
I'm looking envious at the other Mirage case and wish there was a way to swap so I got the space I need.
I have enough custom builds, mods, cases so I'm realy interested in something solid of the shelf stuff for this unit... waiting for Elbox to pull out a fat A4000 bigtower soon.
