This new style of HP desktops, replacing the old black ones, is smaller and a little less expensive. But the expansion options are extremely limited. No room for a second optical drive, or a SSD, or a second internal HDD. Only two RAM slots on the motherboard. It does have a graphics card slot available but with the little 300 watt power supply will limit you to low power cards. No gamer cards for this computer. Overall I’m not so sure that the new models are an improvement. I’m sure they are cheaper to manufacture.
