Hello Sobremesa, thanks for joining the Intel community.
I glad to inform you that Intel will provide warranty for your product for three years, starting from date of purchase; however it will be necessary to check the Warranty policies in Israel since sometimes they vary from GEO to GEO. http://download.intel.com/support/processors/sb/english_3yr_warranty.pdf
We always recommend customers to purchase our products from authorized distributors. The following link will provided you the list of Intel® Authorized Distributors around the world. Intel® Authorized Distributors

Here you can get warranty information for Intel® NUC products: http://www.intel.com/content/www/us/en/support/boards-and-kits/000005679.html
You can apply the warranty even if you are in a different country within the same Geographic area, i.e. you bought the NUC in the USA and you are in a different American country but, if you are in Europe you will need to send the product back to the USA.
Keep in mind that you will need a valid invoice from the seller, in order to get the warranty, i.e. if you bought it from a friend; it is probably that the invoice would be under his name.
If there is anything else you need, please let me know.
