The Opus project is a "Falcon" generation motherboard designed to fit in a Xenon case. You can expect an 90 nm GPU but a 65 nm CPU. Opus solves a major hardware recycling and inventory problem since Microsoft currently has millions of used Xenon cases from RRODed dead systems and this lets them use most of the good parts from the millions of dead Xenons but with a newer tested more reliable motherboard.
There is no HDMI on Opus since the Xenon cases don't have openings for the port. Opus is a third generation Xbox 360 in the case of a first.
I would trust an Opus Xbox much more than a "zombie repaired" Xenon since you are getting a fresh motherboard. These will probably never be boxed and sold directly to the public in stores so the only way to get an Opus motherboard is to turn in a RRODed dead Xenon in late 2008 and you might get one returned. Opus is the "Zombie Xbox" killer. It's the recycle repair special and is the sort of repair and refurbished Xbox 360 that they should have had done in the first place.
Visiblement c'est une nouvelle CM, nom de code OPUS, censée être plus fiable, pour recycler les coques non HDMI des 360 mortes sous le ROD - paix à leurs âmes. Ce qui explique que ce pack soit en édition limitée.
