The only one of those I have experience with is the M9. I used that case for my GF's build, got it for $50 w/ free shipping. I feel it is a pretty good case. Has good airflow, and the mesh at the front helps stop dust from getting in the case. I have a Tuniq Tower installed on her CPU and the case holds it with a little room to spare.
I am not a fan of the slots on the side panel, but I guess they help with airflow???
Another thing I like about it is the PSU is at the top of the case, not the bottom like the 900, and 690. Not that that's a bad thing, I just prefer top mounted PSU's.
Here's a pic of my GF's setup inside the M9 case, I had to paint it though, it just looked god awful with that plain silver.
