An Open Letter

I'm building a computer for the first time in my life and I'm doing it by myself which arguably may be a mistake. I've already had to force in a couple pins onto some headers because there’s a fan in the way and I didn't put these ahead of time, but so far things have been going not catastrophically. I'm a little bit worried because I haven't tested anything and I kind of was banking on the fact nothing would fail and so I don't really know what I'd do if that happens. Live and learn!
