Hi foosi, that's interesting. I've found Geekbench scores to be quite repeatable, regardless if the system has just been started, running for a while or just woken from sleep mode. Maybe your system is still occupied with running startup scripts, loading applications or connecting to networks while you run Geekbench straight after a system start, thus affecting your Geekbench score. Hi mrmatt, I think besides the power issue, a standard graphics card wouldn't physically fit inside the slim ISK-110 VESA case. Hi magdale, unfortunately I can't test or comment on using airplay because I don't have access to an Apple TV. You shouldn't have any problem using the Intel I3-3225 processor, which includes HD4000 graphics. In fact, I've just installed (last week) an Intel i3-3225 processor in another Hackintosh build, based on the older GA-H61N-USB3 system board. Even this mixed configuration (Series 6 system board with Ivy Bridge CPU) is now quite easy to configure, thanks to the additional support now included in MultiBeast (currently at version 5.2.1).
