I am trying to connect to the internet and connect audio and video on my home office computer to my home entertainmnet system. I have an Inspiron 531S and have become aware how dreadful my options are (or lack). I need a low profile card. The PSU is very poor and hard to upgrade. I have seen refernce to the fact that some video cards require external power. I have an extra modular power supply with a lot of optional cables. It won't fit in the case but I could easily snake a cable in to power the auxilary power of such a card. It will need to have an HDMI port.
