Is Computer hardware a good possible niche pick?

Hey everyone, so brand new here just trying to make any cash I can to help out with rent and afford dog food. I've been reading the easy $100 a day pinned post and have been having a hard time figuring out a niche. The only real thing of interest and passion for me to write about is PC hardware but I have no idea if this is actually a niche that would work well. I feel as though it probably isn't, but I have no clue on what else I could make a blog about.

I tried looking on ClickBank, under Topic or Niche. I'm a bit confused on the use of clickbank also...is it something I should be using or is it a scheme?

I guess I'm really just overwhelmed. I'm not really understanding where or how you make money by pointing people in the direction of your blog.

Any help would be much appreciated and I'm sorry if this is in the wrong place.

Thank you.
