really thanks alot, you helped me narrow quite a bit
in my country not my places there are good seniors to learn from. People are pretty selfish here (in my country). 
lets say the site host something like uploading of images can be up to 1gb maximum - are you able to narrow that?
is like a site for users to upload their information and upload a picture but the IO can be alittle on the high
yup, will be doing NLB on my webserver (IIS)
3 servers = 3 physical servers right for HA?
