Total noob starting out

Hi im a total computer noob. I wonder if anyone has a ebay buying list for the hardwhare parts.

I got this so far - QO-100 Bullseye TCXO LNB - Ultra Stable LNB for QO-100 and Ku Band Satellites | eBay

I’m building this because i think the internet is going to be more unstable in the near future for a period.
