Hardware Recommendations for realtime voice and a simple personal assistant/organisation agent.

Hi Guys Been looking into building a localLLM box to run at home to do things like ingest emails and monitor various communications then create events, reminders and tasks for me. I'd also like to explore communicating with the system via realtime voice chat (I don't expect it to be real real time, a short delay is fine if I can communicate with natural language). If this isn't feasible for the home player, please stop me now. I will not be doing any coding or am happy to pay for a few tokens on a frontier model if I need deep reasoning.
