What do you need three for?
Good question.
Gonna sell them for double on ebay..... only kiddin'
All Commercial use thus far and a cheap and easy way to upgrade our existing macs some of which are getting old and if they fail would be a problem while getting more power and future proof connectivity and upgradeability.
Graphics is not a priority nor is Yosemite a requirement!
Intel 4000 is more than adequate and probably more than existin gmachine have. Many of our machines are still on Snow Leopard too.
1) A server running our software suite with a requirement for RAID 1(headless).
2) A flexible Workstation i.e. VM usage. (Possible upgraded to SSD )
3) A Dedicated Security cam & file sharing box that might also be used as back up workstation (RAID 1 again).
Also 3 machines using less power in total than my both my old M$ server HP box and 08 Macpro is always a plus.
So that's three spoken for already.
Apple don't seem to value the commercial applications of this form factor (which they created and others followed) with their recent mac mini charade but I do.
However the 2014 base model is also interesting proposition as it's value oriented proposition and you can trade lack of upgradability at that price point but the higher models no way.
Paying more and not being able to addition HD or more memory in the future is a big no no. While the servers still available they're the one to get.
Also I wouldn't mind one for home too and personal use that I would SSD upgrade.

Did you see the post where the person says the 2.3Mhz runs quite a bit cooler than the 2.6Mhz models? The extra speed comes at the cost of much more heat and potentially heat related issues or a shorter life. I'm sticking with my 2.3Mhz purchase. I was trying to snag a 2.6 model myself, but the 2.3 may be the best deal overall.
I'll keep that in mind. The 2.3 are the only one becoming available now and all the base server model. Which is fine.
