I'm glad to see that we share common thoughts.
As you are introducing this topic, let me say that besides what your are saying (that I totally agree) I may add that Epia hardware may act as small, reliable and affordable Core unit for all those situations where a top level server is not applicable or simply oversized.
Using a dual Xeon with 10 Terabyte RAID5 disks system in a loft or in a standard apartment sounds to me like to go fishing onboard of a cruiser ...
This also introduces the very next question, that actually I think you already asked with a different perspective (when you said you want to install a core in your car).
What about a house network/system with more than a core?
In other words why not thinking about scalable or stackable core system, that allow to increase home automation services by adding one or more cores to existing one? :idea:
Is it something that may have a future, or may it be the case to buy myself an extra air conditioner to cool me down a bit? :lol:
Looking forward to have your impression
