You can use i7 with 4GB ram 64gb ssn 2gb/4gb video card(Graphics card) with some cooling fans.
What is this wrong advice you are giving?
1. You don't need an expensive cpu like an i7, I built mine on an AMD sempron which cost only 2k
2. No need for an SSD. Run BAMT or SMOS thru usb bootable
3. GBs do not matter for a graphics card when it comes to mining. You need a high end AMD card like the R9 390x or similar.
I have seen you post on other topics too just for the sake of increasing your post count while not contributing anything to the conversation.
Please refrain from doing so.
