Check With Other Pseries Servers Users First
With so many choices these days for servers, how are you supposed to find the right ones? I suggest asking other companies what has worked for them, and what has not. Those will be the people to tell you honestly what they think about the pseries servers or the iseries servers or anything else that are out there.
I would not want to take the word of a salesman who is just trying to make a sale. He will not be the one with the headache if the server crashes during your busiest time of the year. I put one of the pseries servers into my art gallery and I have had no issues but my brother put one of the iseries servers into his craft store and he swears by them.
Now, I would get many more opinions before making your mind up, on which server is right for you. You can even check out different reviews that are on the internet. People will definitely tell you like it is, when you cannot see them. You could also price different systems while on the web. That way, the pushy salesman is nowhere to be seen when you are sitting on your own computer in your own house.
