Everyone has to put their own value on their own time and effort. In the past, I have painted my own houses, inside and out. But now I am seriously considering hiring someone to do some paintwork simply because I don't want to put the time and effort into it myself. It will certainly cost more to have someone do it, but I consider it worth it since it will free up time for things I would rather be doing.
Same with maintaining my vehicles. I used to do all my own maintenance - to include pulling transmissions, swapping out flywheels, replacing U-joints and more. But never brakes. I want someone I can sue if something goes wrong!

But now, I just have my mechanic do all the work - in part because I can afford it, but also because I value my own free time more.
Just finding the right power supply is a big project for me (sames goes for RAM, CPU, etc) so hard to do all at once
Doing proper and thorough homework researching components is indeed, if you want to do it right, the most time consuming and even challenging part of building your own. This is especially challenging if one has a touch of OCD.
You might check out
PCPartPicker. It is a great tool for beginners and experienced builders alike. One thing it is good at is ensuring the various components are compatible. It also determines power supply requirements based on the parts selected.
You seem to be hung up on "up front" costs and I would urge you to look at costs strategically (long term) instead. With careful shopping,
you WILL save money in the long run simply because you will be able to perform various upgrades over time, allowing the computer to keep evolving to stay current and to meet your changing and evolving needs. That helps extend the overall lifespan of the computer. And that saves money in the long run compared to the alternative which is buying all new more often.
I am used to getting hold of some junk and then slowely upgrading with second hand parts; my present Core 2 Quad CPU was around $25 with postage
all this fun would be lost.
The process and fun is very similar. It is just brand new (and under warranty) parts instead of used. And of course (and again with careful research), shipping is free!
The only thing I do NOT recommend is buying your new components, one-by-one, slowly over time. Instead, build up your budget until you can buy everything all at once, or at least over just a couple weeks time frame. The reason for this is primarily because warranties typically start at the date of purchase. You don't want your motherboard warranty to be 6 months old, for example, before you buy the CPU to mount on it. Also, many retailers have a 30 day (or something similar) "no-questions asked" return policy - where you can return something even if you just change your mind. If that expires, you may have to deal with product manufacturers' return policies instead, and/or if no fault is found, you may be charged a restocking fee.
