I hope it comes out fairly soon, because as of this week I'm ordering my motherboard and hard drive. Those are the last components I will need for the actual computer, with the exception of the power supply. For the touchscreen and new headunit I'm going to hit dad up since he sold my $1200 dollar rockford fosgate system with my celica.
I read on this post, as of 9-19 they estimate 8 weeks until they will start shipping the M2-ATX. So hopefully it comes out sooner than expected, because if all goes well I will be needing a power supply soon.
I see that the M1-ATX is now listed back at mp3car.
