You mentioned this in a couple threads, now. Can I ask why you’re so worried? From what you posted, I take it that you used to assemble your own systems in the past. For me, while the frequency of doing builds has dropped significantly over the years, I find modern PCs very easy to assemble compared to the old days.
Cases aren’t sharp anymore, standards are more prevalent, connectors and sockets are more robust. Software is more standardized and you don’t have to fool around with the bios or an autoexec file as much, or at all.
The options are arguable more daunting, but it sounds like you had no issue with the selection/shopping part. I’m curious to know more about why you decided to farm out assembly, this time.
