I think your HD price is off, and time capsules have not had a history of reliability. However, I've also run a linux/netatalk box, back in the snow-leopard days. It did "work", but things would get screwed up for me if I ever closed my laptop whenever a backup was in progress. I ended up using an airport extreme for time-machine backups. It works well. I have it connected to a Sabio raid box[1]. I don't think apple advertises that the extreme works for time-machine, but it's basically plug-n-play type setup. No hackery required. Just an external disk with USB connectivity.
