Think the name of the desktop is something like that. I currently have an HD 5450 and I'm looking forward to upgrade to the Geforce GTX series. Other than the power supply which I will update, I'm worried if the video card will fit or not. I measured the maximum hight for my computer, and it seems to be 11.5 cm. I'm not sure if I did that right, since the cards I want are 11.1 cm. I ask the seller online and his said no HP destops can run the GTX 580
