This question already has an answer here:
I'm looking at purchasing colocation services for a Mac Mini with A specialist colocation company - but as of yet I have no experience with OSX Server for hosting websites. I'm looking for a less involved way of hosting up to 80 small (1-20 page, <1000 daily hits) WordPress websites for my clients. All of the websites use caching aggressively.
Does anyone have any experience using OSX Server for WP hosting / any ideas as to how many sites it can comfortably (ie minimal loss of speed) handle? My intention is to purchase one with an i5 processor and 16GB of RAM.
