Pretty sure that 5RAM PC don't exist :x
But I get ur point, think someone mentioned me issue with credit cards in Egypt, from before.
I kinda can relate to how PC parts are expensive, since I just recently compared prices with one friend from US, he paid 600$ for 1080, while here 1060 costs that much. 1080 is 1300$ or above (insane)
Steam has own market. U can trade cards and such. CS:go keys. I do remember ppl from game called Spiral Knights used to sell in-game items for CS:go keys and then sell CS:go keys on market.
