The reason for the linear rails has been gone over but it's also to enable a speed increase basically. The more sturdy and less flex the faster you can print without losing resolution.
As for the idlers/pulleys and belts, belts are important because the cheaper the belt the less fiber and more elasticity which is bad for accuracy and print resolution. The idlers and pulleys themselves are fine buying cheap but its the bearings that make the difference. I bought a bunch of cheap ones and all the bearings were crunchy and not smooth. They would be better to just use bushings than terrible bearings. I ended up going to the hobby store and buying good RC car bearings and fixed the issue but its a pain. better to just buy decent ones with better bearings.
While these things all seem like small details, they add up and end up compounding to cause problems that can be avoided.
For the heated bed, I completely agree it would probably be cheaper to buy the mosfet than to buy a 24V power supply that would do the job. I'll probably do that.
