Pastrychef, thank you very much for your installation information. I too was blown away when I found this computer (8300 SFF) - I originally purchased it to get the processor and put it onto a DH67CL board. When the Intel board bricked during bios update, I was forced to use the 8300 as a stop gap - it has now become my main computer, with dual boot ability, for all of my main audio recording and other intensive projects. Using the HD4000 via displayport for one 27" display, driving another 27" display from a displayLink USB3 dock from Targus that I found at a London Drugs (Canada) for $80... appears they didn't know it needed a driver for MacOS. I've added a firewire card for connection to my audio interface. Similar to you, I don't really need more computers, but I feel drawn to buying the mini tower version just to have more drive bays.
