意大利采购需求：工业计算机制造商，坚固型计算机制造商

I'm interested in receiving a detailed offer for 5 units of a specific tablet model made by Advantech, with a screen size of 17 inches. Please include your best pricing options, lead times, and any available warranty or support services that come with the purchase. Additionally, it would be great if you could provide information on bulk order discounts or any ongoing promotions that might apply. If there are different configurations or accessories available for this model, please feel free to include that info as well. Looking forward to your prompt response!
