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
Go here. Select "drivers and software". Then select "Detect your Product". IT'll find the exact model you have. Post it up here.
