Hi, I reckon the main consideration is (depending on size of the organisation and knowledge of the IT staff) go with what the people onsite are familiar dealing with.
So an i7 iMac with SSD may be sufficient, I have a number of sites running off a 27" quad-core iMac or 2012 Mac mini. I suggested they would get better performance from a Windows box but none of the clinics' owners have experience with Windows so that suggestion has been always declined. Admittedly these are small databases (3 - 10 GB) with low user numbers (5-15 users).
