Yeah, I've got one. I saw it at a local PC Club here as well (although I ended up ordering it from ClubIT) and, like you, thought it was a little weird looking. But if you give it a chance and put a system in it, it really looks great and performs well. It has a lot of functionality for the price, even with its drawbacks. In short, here's my opinions of its strong (+) and weak (-) points:
+Excellent ventilation. Two huge vented grills on the side and several slits on the top for additional circulation. There is no fan on the side, but you could rig one up easily to make use of the side grills with a Sunbeam PCI Anywhere kit.
+Sturdy integrated carrying handle. It's comfortable to carry and makes moving the system around very easy.
+Two 120mm fan mounts. It's the standard, of course.
+Styling. Like it or hate it, you've got to admit it's one of the most unique cases around. I'm personally a HUGE fan of military-styled things. Mine definitely turned heads at the last LAN I went to. I've got an ABIT Guru Panel in the top 5.25" bay and it looks absolutely incredible with the rest of the system.
+It's SECC. I personally view this as a plus since it's sturdier than aluminum.
+Positioning of the integrated front inputs is good for LANing in my opinion. If you put the case to your left, you can plug in a USB keyboard and a mouse in quickly and easily.
-Only comes with one low RPM blue LED 120mm fan in the front. I took it out and put two 120mm red Tricools in.
-Somewhat heavy for a LAN case. If you work out at all then this won't really bother you. If you have a neck that resembles a stack of dimes, however, then it might be too much to handle.

-Can get dusty, no fan filters included. All those ventilation holes are terrific for circulation but they can also let a lot of dust in. Canned air it away once in a while and you should be okay.
-Only 1 external 3.5" drive bay. I personally can't see anyone needing more than one, but if you've got several then you may want to take this into consideration.
-HDD Cage is somewhat small, 3 drive capacity. This isn't a problem if you're an average guy (like me), but if you're a RAIDing fiend with multiple terabytes of storage, look elsewhere.
Make from that what you will. If you're still curious about what an Ammo system looks like, let me know and I'll put up a few pictures of mine.
