It looks like a good system. The one caveat is the PSU. Nvidia recommends 500w for the 2060. Dell is providing a 460w PSU. Dell also does not provide any details about the PSU. If it's a generic OEM PSU then it could be problematic. The most common cause of system failure or unreliability are cheap, generic PSUs. For a high end system, you probably want a brand name 80+ Silver, Gold or Platinum model, such as Seasonic or Corsair, rated at 500w or higher. That's especially true if extra components, a second GPU or upgraded GPU might be added. A second 2060 GPU would push the PSU requirements into the 650w-750w range. It looks like that case will take a standard ATX PSU but I would check on that as well.
