To my fellow irishmen who are in the same boat as me who are popping up here and there, I created this thread on /r/ireland :
https://www.reddit.com/r/ireland/comments/l0ll36/looking_for_info_on_import_duties_for_a_graphics/
By no meant an authority on the Brexit **** show that's a mere inconvenience to us, or import duties and all that, it does kind of point ( albeit word of mouth from those that have been through the system) to the fact that we've paid Irish VAT already, and that there are no import/customers duties on computer parts. The above quote also mentions that since OCUK is registered with revenue.ie, that we've paid the tax already. If we paid the tax, and import duties are sorted, then we should be good once or orders are no longer on hold. ( ordered 7th of Oct here, still 1000-1110 in the queue). Seems there is at least one brexit troll in the last few comments, ignore him, he cant get a self congratulating **** out of it, if you do. Might seem like a political comment, but its not really. I'm just trying to help out others who bought from OCUK as well, in a quandary, not of our making.
