This is a decent setup. The only limits you'll have is the 10 GB database max size 1 CPU and 1 GB of ram (used by the server).

I've had this setup work well for years on a in-house ERP with 10 users before they "upgraded" to SAP.

A good tuning tip for access is to have a timestamp column on all the tables (see the difference in the query generated when you don't have it on a table with lots of columns). The difference on CPU is really noticable both on query execution and plan compile.
