Need help choosing mid tower case

Hey guys I need help choosing a mid tower case that will be used for mostly gaming/media. My biggest concern/factor is defnitely weight because I will be carrying it around A LOT. I am hoping it to be under $130 and these are the cases I have been looking at so far but am not sure which one I should go for.

NZXT Lexa

TT Tsunami

Ultra Aluminus

I am also open to other suggestions so feel free to recommend other cases as long as it is light weight. I was leaning a bit more towards the Aluminus since the extra money can be spent on upgarding other parts, what do you guys think? Thanks

Since you travel with your computer and you plan to use it for gaming, I would go for the Lexa since it has 3 120mm fan ducts for good cooling and includes carrying straps.

The second case is nice enough. If you're on the move with it a lot, that first case says it comes with a strap. I'm not crazy about doors on cases, personally.

Here's my addition:
CoolerMaster 690

If I go with a steel case, would you say the Antec 900 would be a better choice than the CM 690?

I must say, Savage's pick is the best of the bunch.  The first 3 are rather ugly.  (I'm not judging on looks alone, Savage's is just a better case all around.)

I love my Antec 900 has kept my innards nice and cool

^ Also a good choice.
There's a few things I prefer with the CM690, big one being price, then there's some additional features to it, too.

if u really have the money to buy a case then buy this one its the newer version of chief's antec case

Wow, we have those @ sub-$200 here in Canada. Probably not something you want to carry around often.
If you're interested in those Antec cases, you should know there's a smaller/cheaper one, too.

ouch.. you want a full tower?? I have 2 8800GT cards in mine with 2 500 gig HDDs and still room for 4 more HDDs   the Antec 900 has plenty of room in it from what I can tell.  Although if you wanna drop that much on just a case be my guest.. it is your project
