https://www.thinkworkstations.com/products/ The new P Series workstations from Lenovo look like they may be the best designed towers from any of the major players in a while time. Apple is not the only one who can design systems, and it looks like Lenovo spent a lot of time trying to do a lot of things right. Two socket systems that use the latest and greatest tech are not going to be cheap, but cheap is not really what it is about in markets for such systems. My guess is that Apple still has the correct read on the overall market. For the huge majority of people/businesses, a workstation that has a single socket (currently 12 cores; maybe go up to 14 or 18 before too long), two workstation-class GPUs, 64GB ram (probably will be doubling with the next generation), and a TB of PCIe SSD is more than good enough for most. And the fact that it can sit just about anywhere around a desk and be unobtrusive and quiet is a huge plus for a lot of people. But if you want modern dual sockets (let's face it--not everyone is re-writing their software to take advantage of GPUs; it is very hard in some cases), the increase ram amounts that come with two sockets, the freedom to use PCIe slots, plenty of drive options . . . and you still get a system that is reasonably quiet (though I doubt as quiet), is easy to service and is from a major player who will provide support . . . this may be your best bet. It is not as small and does not run (in a supported fashion) OS X, but it looks like a winner for those running other OSes.
