Back to the OP:
Yes, assembling a Raspberry Pi and putting it into service as a
Squeezebox replacement is a 20-minute DIY project, but that assumes that
you already know what parts you need and how to put them together.
Here is what you need:
1. Raspberry Pi 2, Model B
2. Hifiberry DAC+ OR
2.

Absolutely! But because it is cheap and has a cheap-looking plastic box,

Bummer, now I'm really gonna bug them about making a digi+ "Pro"
I wonder if the linear 5V is a very pure source for the 3.3/1.8-- as
reading some more on Daniels thread, he could not measure any noise on
the 3.3V on the pi, so it's very well done... not worth trying to
separate it, add a header for 3.3V etc...
Any thoughts?

It is simple. 20 minutes to put it together and have it playing music.

Just want to mention that there's this:

You'd probably want to add a USB DAC and it's expensive compared to the
DIY Raspberry Pi solution. I
That doesn't replace the Transporter, as there is no DAC.
If you have to buy a DAC, there are all kinds of options. You can ever
build a Vortexbox out of old computer components.

OP says he uses iPeng, so my guess is that lack of a screen won't be a

Obvious low cost solution is a RaspPi running piCorePlayer plus
HiFiBerry Digi+ (cost for both is under $100)
