Yesterday I looked at Git. This is a version control written by Linus Torvalds, and I'm not going to pretend I'm an expert. However, github (https://github.com/) seems to be the favored place for open-source repositories.
Great! What if I want to keep my code private? Github allows private repositories for $7/month.
This might be a competitive price to Amazon Web Services (http://aws.amazon.com/) - although for the CPU bandwidth, it's more cost-effective to build a machine from scratch (I'm assuming their prices haven't gone down significantly since I last tried them about a year ago). It's certainly competitive to Linodes which go for $19/mo and up.
So how cheap can you build a PC for nowadays?
If you're not in ANY hurry - take a look at the quite awesome Raspberry Pi:

Turnaround is months from placing the order, unfortunately.
You'll need a power supply and SD Card - which will run a total cost under $60. For small projects that you want to keep private and quickly set up a git server, this looks like the right way to go. There are also rumors of an Android build for Raspberry Pi, and those GPIO lines... something about them calls out "make something!"
