I purchased the HP Pavilion a600n for my son's computer. This desktop PC has many of the features of my HP Pavilion 716n, and although it has a slower processor than my computer, I find that it runs programs nearly as quickly. The HP Pavilion a600n has an AMD Athlon XP 2800+ 2.08 GHz processor with an advanced 333 MHz front side bus. It comes with 512 MB of RAM installed, with a speed of PC2700. The compute is upgradable to 1 GB of memory. I have no experience with the hard drive, as mine came without one, however I was able to install a new hard drive with ease. I have had difficulty with the CD-RW/DVD combo drive, most likely because this is a child's computer, and the boys have been too rough with the drive. The video graphics are excellent, with up to 64 MB of allocated video memory. I use the integrated 10/100 Base-T Network Interface Ethernet card on a daily basis in my wireless home network. Since this is primarily a gaming computer for my sons, the integrated AC97 audio is also a huge plus. There is a 9-in-1 card on the front with a USB interface and a digital media card reader which we use primarily for using a flash drive with the computer. I ordered the system restore disks from HP, and the software reinstalled like a dream. The HP Pavilion a600n has been an excellent computer for my two children's gaming needs.
