Well it looks like Apple finally replaced the Mac Mini's with a nice new one with up to 64GB RAM and 2 TB flash drive! In reality, you can get configure it with 1TB SSD and 16GB RAM i7 cpu for a nice small FileMaker Server for about $2,000, which is not bad. If you have a fast local area network, you can even connect the 10 GB ethernet option!
Obviously this is not for big solutions with a lot of users, but small solutions and development servers, this is great! Caveats are that it is consumer hardware and not server hardware, etc. But I can see a lot of my small to medium sized clients finding this fits their needs well!
