When it arrives will the operating system already be installed? I ordered a SSD (240GB) and HDD (1TB), will the operating system be installed on the SSD automatically or should I reach out to PCS to confirm? Is there any point in partitioning either of these drives? What will this be like out of the box? Is there much set up involved? Does it take long to get it all up and running? I don't mean actually hooking it up but rather when I turn it on for the first time. What can I expect day one basically?
