Hi, I've read that the classifier for computers is 台. However, desktop computer (台式电脑) already begins with 台, so I was wondering whether there is another classifier for this type of computers. I have two desktop computers. Which is correct? 1) 我有两个台式电脑 2) 我有两台台式电脑? 3) 我有两部台式电脑? , any another option? Thanks in advance, G.
