Anyone have a NAS device that runs a quality version (not a hugely paired down version) of Twonky so that I can serve my HR20 and XBox 360 solidly?

Recommendations much appreciated.

Have looked at these: http://www.twonkyvision.de/Products/TwonkyMedia/nas.html#pre-installed

The Lacie doesn't sound good (only Twonky 4.3, and not full version)
The QNAP looks good, but kinda pricey.

Anyone have experience with this?
