This workstation is an excellent home, small business computer.  It's noiseless and fast.  Tried to upgrade the RAM to 64K but in doing to started a noisy PS fan.  Took out the extra RAM chips and it's great.  Much faster than my 8 year old computer.  Was suprrized to also get a mouse and keyboard with the purchase but they were Dell products. .  They worked OK but would like to have HP pure system.
