Undeterred by lawsuits, Psystar this morning launched the Open(3) as its latest overt Mac clone. The system drops the conventional mini-tower for a slimline shape but is technically faster: the stock model uses a 2.8GHz Core 2 Duo desktop processor and now has the option of up to a 2.53GHz Core 2 Quad. Psystar further gives the clone space for a small dedicated graphics card and options for 802.
