help me to chose a case!

Definately Antec 1200. Xaser doesn't even come close.

Between thouse two, the Antec 1200 for sure..

Antec 1200 just because in my experience - Antec quality far surpasses thermaltake.

Everyone is going to vote 1200, and for good reason. The Xaser is alright though the looks aren't up everyones ally.

1200!!!!

I ran a thermaltake xaser for a few years with no problems. The airflow was ample, the case was absolutely huge. It was a 4 ton fat steel beast, but it held everything that I could ask it to.

As far as choices between the two, I would go with the 1200 now versus the Xaser.

get the antec and love it.

As others have said, I recommend you go with the Antec 1200. However, if you have some more money, you should check out the Cosmos S. It's a big, solid case that I've owned for nearly a year now, and I absolutely love it.

Another note, never go with Thermaltake products.

Another vote to Antec 1200 in this case.
