I'm looking to purchase a new high-performance mining device for my operations. Specifically, I'm interested in a model from a well-known manufacturer that is reliable and efficient. The device needs to be suitable for deployment in Latvia, and I'm especially keen on one with a single port for streamlined connectivity. Could you provide me with the current availability and pricing details for this product? Additionally, it would be great to know the shipping options and estimated delivery times for Latvia. Looking forward to your prompt response so we can move forward!
