This RAM.

This GPU will also be ok. You wont be able to play many games but you have the option of upgrading your GPU later.

All of this came to a total of $434.95 CAD.

 

I would also recommend most of these parts, ESPECIALLY the Z9 Plus. It's the case that my rig uses and I absolutely love it.
