Laptop Core i3 based server for small clinic practice

Newbie here. Planning to start using Openemr for a small non-US clinic practice using a Core i3 based laptop. It will be and onsite setup working only 12 hours a day, average users around 5. Will these specifications help get me up and running:
-Core i3 6006U
-4 gb ram
-1000 TB HDD
Laptop can be upgraded to 16 gb ram and i guess to an SSD, but we are on low budget.
