I just completed putting together my new build using an Antec P182 case. Wow... I love this case. The inside of my build is *so* clean. All the big cables are run behind the motherboard tray, and tie-wrapped down securely. Even the the huge ATX style power connector is run behind there. And this is my first build with SATA, and I just love how clean it can make the cases, vs. traditional old style IDE cables (contrary to the original poster's comment, I have used rounded IDE cables in 2 of my past builds and have not had any odd issues. 2 builds isn't a definitive sample, but works for me in this case )
The only thing I dislike, and I don't think I can prevent is the SATA power supply connector issue I have. My PS is mounted on the bottom of the case. As such the cables snake up from the bottom, rather than fall from the top so the orientation is opposite of what is expected. So, instead of having a nice clean chain from the bottom of the case to the top, what I end up having is the wires go into the top of the SATA connector (which is plugged into the 1st drive at the bottom of the case). Repeat for the next 2 drives up the line, going towards the top of the case. Not reallyi a bit problem, but it just looks a little odd and I'm not sure if it strains the wires a bit.
I had to remove the fan in the bottom chamber becuase the Enermax Galaxy supply I have is big enough that it would bump into it. Not really a problem, the bottom chamber is empty except for the PS in my build. However, the mount for the power supply assumes a "standard" size supply - the Galaxy is rather large, and as such putting the mounting bracket over the PSU in this case goes right across the center of the Galaxy's fan. Not really a big problem there is still quite a good amount of airflow. Looks a little odd, but no one will see that ;-)
