Thanks for the reply.
I don't watch videos. I got the card mainly for a CAD program (SolidWorks 2008). The other choice was a used CAD card, like the Nvidia Quadro FX3400. The newer consumer cards presumably perform as well as a CAD card that is a few years old.
The more I study the differences between cases, the more I lean toward the CoolerMaster. It is 20" long, compared to 18" for the Antec, which avoids conflict between video cards and drives; although, I can't see that I will be using more than one video card in the near future. I will look into the XFX version. The box I have is unopened, and the store is very liberal with returns.
