I'd stick it in your office - $300/mo is still $3600/yr...
Other option I'd look at is spot gpu instances on aws - then it's hosted and you don't buy anything - and potentially you could shut it down part of the time although you're charged a full hour for each partial hour...
But the thing is I am not sure if amazon keeps a spot-instance reserve (i.e. what happens if all the spot instances get turned into on-demand ones over, say, a month and suddenly your service is shut down and you keep waiting indefinitely[you'd probably wait for around 24 hours and then try to get an on-demand one - which is 11x more expensive, costing around $600/mo for a shared gpu. and if you can't find an on-demand one, you will be offline for around a week until you figure out a way of provisioning a gpu instance from another service provider, which will probably cost you a lot more, but at that point you will have to do it not to disrupt the service for so long])

I don't know about AWS for this use case, if you use it more than 50% of the time I'm sure costs will be much much higher.
Actually he is right - gpu instances are pretty cheap if you use the spot ones. http://ec2price.com/?product=Linux/UNIX&type=g2.2xlarge®i...
