I used to do it too, but with cloud Exchange running a total of $10/month for the two mailboxes I needed, it is much cheaper than hardware + electricity + licensing... if you're licensing Server 2012 R2 and Exchange properly, the cost of those alone exceeds $1k.
Started a long time ago, when I used it as a lab environment for the most part. Then moved into it personally, started hosting other services for various functions I needed/wanted, and it stuck. I am ok with the cost when I control the entire environment from AD to IIS to VPN to Exchange, etc.
I long since moved on from netadmin stuff, but I still tinker.
