@Yasamoka, there is no Customs duties on Computer parts, am 100% sure cuz I always get 0% on every part except phones and their accessories which is 5%

Do not search for words like "Computer, Hardware, PC...etc" cuz you'll find nothing, it's listed under the name "Integrated Circuits and PCB's" or something like that I don't remember...
