i was in a similar position as you not long ago.
its sounds daunting, but i couldn't believe how easy it is.
my first build took about 4 hrs, with about 1 week of watching vids on google about the components eg. how to apply thermal paste
etc...
now i can do a build in around 1-2 hours,
its just a confidence thing. you need to lose your build cherry to understand
and i will admit, i have forgotten to turn on the power switch on the psu once, realised after 4 hrs of panic
