Not sure about location, but if you want a dedicated machine, another option might be Mac Mini CoLo. The long view from Aus prevents me from having an opinion about their reliability or otherwise, but the idea of CoLo (Co-Location) is that it's your machine in their datacentre. They provide power, environment control and connectivity, and you provide the machine.
I've had excellent experience with Triple8. Can recommend them.
Triple8 is well priced, but I ran into a licensing problems with them and referred it to FileMaker. Maybe it was a just a one time oversight by them and not intentional. If someone from Triple8 is on here, it would be good for them to speak up about their corporate policy on licensing and hopefully it is different than my personal experience.
