I believe you have a 300 watt PSU and your best Card in a slim SFF design for around 100 that will be able to be run by your PSU is a Nvidia 9600GT.
Go to Newegg.com and pick up a Radeon HD 4550 with either 512MB or 1GB RAM for next to nothing. Not the fastest card around, but handles most anything with acceptable results. Cool, quiet, small. Just what you are looking for.
