Working without PDM - what affects performance when using LAN server for file read and write

Our company is first going to start the use of SolidWorks without PDM and having CustomTools for product numbering etc. Total number of SW users will be about 5 at first and we plan to use the company LAN server to write and read SW files. Being quite a novice concerning networks, what are the critical factors to ensure fastest connection possible between each user and file server in company LAN?

We should be having notebooks with Gigabit ethernet cards. I know the cabling must be Cat5e between the notebooks and the switch. What should be taken into consideration when looking for a server and the switch for the best performance? Thanks.@
