No offense, but are you pulling off one of those "just buy it" Tom's Hardware pulled off recently and went super well for them? Like RDNA2 is coming soon and Zen3 is coming soon. Unless this is to make Intel and nVidia happy, this guide should really be made after those come out to actually recommend parts based on reviews of everything. As is, if just feels like it got rushed out before arguments for Zen3 and RDNA2 can come out. Sorry, but it is paculiar timing.
This is fine but I don't know about this being a "guide" per se. Seems more like a blog with a few helpful tips. Seems to focus more on the "why" for a singular, personal scenario. To be a proper guide, IMO, should go into more detail regarding choice of hardware, what specs to look for, how to check for compatibility, and offer more information on procuring them.
Having an article about picking parts and not mentioning certain specifics?:
Socket types and chipsets
RAM frequency, latency, and channel configuration
PSU efficiency ratings and TDP of components
M.2 drives (NVMe or SATA interface) drives and and their significant performance differences
Cooling methods and components...
I could go on.
I mean it's vaguely informative but again, more of a blog with tips and not really a guide.
