I found this site searching through the internet. I live in a decently small town and getting affordable pc parts was already impossible for your structural engineer student here as it was. Now Im getting into SFF and I want to build inside a Terra but finding ITX parts that are affordable to a student in canada AND in a small town is like impossible.
Welcome! I would suggest to sometimes check pre-owned markets, including the buy & sell section in this forum, reddit, or ebay.
For example, my living room PC parts are all pre-owned: MSI B450i Gaming AC, Ryzen 5600, Radeon 6800, Corsair DDR4 RAM. Only the PSU & case are new. I did this because I know it won't be used that often, thus buying pre-owned gives me better price. I usually buy pre-owned things that still has warranty though.
Of course, only do this if you're aware of the risk.
