I bought an iBuypower full tower factory made computer about fifteen years ago. I've upgraded it about three times. In the past five years I have been building from scratch using a mid tower case (which I eventually gave away), and moved on to a ThermalTake full tower. So I now have two full tower rigs. All of my builds have cost me in the neighborhood of $2000.+ I chose that course because I wanted to select the parts that I put into the builds. Which is of course is the reason most people DIY. While I would rather a full tower, I think the Aurora R16 fully tricked out for $3000.+, is reasonable and what I would expect the price to be. If I stopped building my rigs at some point, I would consider the R16. I don't think that anyone considering buying that rig would be the type of person who would care about proprietary parts. Only DIY people would, and they probably wouldn't buy a factory made rig anyway.
