Probably the AppleTV.
These folks will do it for $300, roughly twice the cost of the drive (but that's probably not what you want).
So far all the methods rely on DiskUtility. So you need to have OS X of some sort.
Still, if you're familiar with Linux, you should be able to use parted to create the partition table, and in theory, dd can be used to extract the data from the original Apple TV. The problem with standard Windows utilities is that most (all?) don't support the GUID partitioning scheme. MacDrive does to some degree, but I doubt that'll be enough. Still, I'm sure somebody will try it sooner or later.
