I am in Canada and these Acer machines are at Costco and are only sold with monitor included. The Intel one is $850 and the AMD one is $150 less. Both have 2G of Ram and a 500G Sata HD. The specs of both are the same. They must be specially made for the company I would think.
Anyhow I have picked up one with Intel. Both these machines seem to be pretty good value. Both have Vista Home Premium but I will keep using XP Pro as I own it and XP Home Edition.
