I am also trying to decide on a case and failing (2 days of research now).
I have read up on the antec p180/b (also their sonata 2, p150, p160w) that everyone seems to go on about and also thermal take's:
tsunami/aguila and Gigabyte's 3D Aurora 2 Aluminum Case.
Every single case gets great professional reviews but there is always 2 or more things that seem to be deal busters to me and yet don't impact the rating (especially on newegg consumer reviews).
For example, the P180 seems to be the most recommended case and yet just about everyone points out that you need a PSU with long cables to reach...that it is hard to cable through the compartment "door" seperating the 2 chambers ...and that ide cables can't reach to the bottom hdd enclosure..also that the p180 is a heavy steal chassis (and no mobo tray--like all i mentioned).
Now the reason i am posting here ...is because i am leaning towards the aquila along with it's faults. This case is the current incarnation of the armor junior that you mention (so i wanted to know about this as a possible one also)..Actually, you mention the full size case variant. So i might be wrong in thinking you really wanted a mid-tower solution.
Anyway, here are a few reviews about your full tower armor (i thought we could share this thread

Lets see if our interests are the same:
want a case that:
-is aluminium (not a deal breaker)
-has no psu installed (though can always swap out --adds to cost)
-Big enough to fit a full atx Mb with room for sli (future) --but small enough to fit under a desk

-has 120 mm fans vs 80mm
-room for a 600-700 watt PSU
-120-175$ cdn price range
-has tool less installation (both 3.5 inch and 5 1/4 drive bays plus pci-slots)
-front firewire/usb ports preferably not located in the middle of the top panel.
easy maintenance.

I have a feeling most will either recommend a lian-li (too expensive) or a p180..
so convince us on the p180. It does not seem as "hot" as so many people say.
Now, if your criteria is greatly divergent from mine..then i apologize for assuming we could share. The info should still be useful to us though
