We currently use a old HP PC (P4, 1 GB Ram) as a LAMP server (running Mandriva 2010). It runs one website, and has a few tables. One table has millions of entries (hourly data for approximately 120 devices for the last 4 years). It works great, web queries are returned within seconds, but we are concerned about the hardware age and are looking to replace the hardware.
We are thinking of using a Mac Pro tower. Does anyone recommend this? Are there any downsides? When running OS X Server it seems that all components would be installed and ready to go.
