Thanks for the warning!!
I have had 0 problems with the modded Macmini, my problems are with the Squeezeserver software. I have issues with faad.exe crashing constantly, despite many uninstall/reinstals and with my computer in another room I had to physically get up and go into my bedroom, click "ok" and come back--sometimes after every song on an album.
My solution for the last 2 months has been using a remote desktop app on my cell phone to hit OK when it crashes, but I'd rather a sleeker solution and had the AMEX points to buy a Macmini. I'm also using a USB only DAC and am presently using a Metrum Octave that allegedly wants to be software up sampled rather then fed the native redbook format from a transport, so there is that variable as well.
