Pros: Definitely FITS in the Dell 530/531S case, you just need to change the bracket to the DVI LP bracket. The card is 80mm wide, the Dell case is 100 mm (HP slimline is 107mm). The fan is not loud (but it is obviously makes more noise than the almost complete silence of the system before). A huge improvement over integrated graphics at low-cost, no need to change power supply for a more powerful card.

Cons: The KFA2 8600GT LP is no longer being manufactured, which is twice as powerful as this card and is the most powerful card you can buy with a 300W or less power supply in a slim system. Chaintech offers one but it is ~80 dollars and heard mixed reviews. I only wish Galaxy offered the 8600GT for 40-50 dollars so that I could have gotten that card instead.

Overall Review: Makes most games playable, but don't expect the most eye candy resolutions. Was able to play Call of Duty: World at War smoothly. At the time of this review, the best graphics card available for a LP system is the KFA2 9600GT (http://www.newegg.com/Product/Product.aspx?Item=N82E16814162016). This card is at a great price, unfortunately it requires a 400W power supply and even though some people claim to have made it work on a lower supply I didn't want to risk it. To Galaxy: Slim-line computers don't come with a 400W power supply.
