My last and final project around the mele a2000: a bit perfect player with mpd and display.  
Arm powered (Allwinner A10).

Updated with a linear and regulated power supply.

~quick and dirty !~

Fully working.

-   Ultra low power – switches to 60MHz on standby and 1Ghz on playback
-   External 12V Fortron PSU + Internal Audiophonics PSUS2 (for the mele only)
-   Automatic power on of the display via the ph20 of the mele + optocoupler Letex LA213 + 12V relay
-   Remote control with lirc, able to mechanize mpd via mpc
-   Bit perfect playback to my Micromega MyDac
-   Connected to my NAS via CIFS (seemless network reconnection)
-   Display the media quality, load, track informations via Conky and flap to the album picture every 30 seconds
-   On the front, power button of the mele, led connected to the mele ph10 (blinking slowly on standby), IR receiver

It runs ubuntu on nand with Xorg + conky.  
The display turns off after 120 seconds of mpd inactivity.  
The remote (lirc) manages play/stop/forward/volume etc…  
The display used is connected to the composite video output and cost … bought at $18 on ebay.  
The new linear power costs $30.

Total pure audiophile player cost ~ $160 ($40 of casing).

The rest of my setup:

-   Micromega MyDac
-   PreAmp: nuForce P8S
-   Crossover: dbTechnologies ASX 18 (with new Muse caps)
-   2 x Klein Hummel O300d
-   2 x RCF ayra 10 sub
-   Cables: rca from sommercable/choseal, usb from lyndi, xlr from viablue NF-S1 + yarbo
