HP Compaq provides quite a few hardware configuration options for these machines. You can get an Intel Core 2 Duo processor from 2.53 to 3.33 GHz, or even get a Quad core at 2.5 to 3 GHz. You can get from an 80 to 500 GB 7200-RPM hard drive, or an 80-160 GB 10,000-RPM hard drive. They also come with either a DVD/CD-RW drive, or a SuperMulti Lightscribe DVD Writer. It has a total of eight USB ports, with 2 in front and 6 in back, plus headphone and microphone audio ports in front and back.
I do wish the USB ports had been placed higher up on the PC, because they are located toward the bottom of the faceplate. The problem this creates is that if you keep the PC on the floor under your desk, there is a tendency for some people to lift up when removing flash drives. This has long been a problem with HP business desktops, and I’ve seen several computers with broken front USB ports because of it.
Should you decide to upgrade this PC, there is definitely room for improvement. It can take up to 8 GB’s of 800 MHz DDR2 RAM, although you will need a 64-bit operating system in order to use more than 4 gigs RAM. As far as expansion slots, it has 3 PCI, 1 PCI Express x1, and 2 PCI Express x16. It also includes a 365 watt power supply that can handle a lot of higher end video cards should you choose to beef up the video to use, for example, CAD software.
