If you plan on using a pc to record music, then you'd do well to know how to build it, and troubleshoot the inevitable problems that will arise. If you can use a screwdriver and follow basic instructions, you can build a computer.
I understand your frustration, but I really hope that newegg doesn't take your suggestions. The only result would be higher prices all around. In the world of business, companies mark up hardware, both for profit, and to offset other costs. Deal with it. If you want a plug and play music pc, you're going to pay a premium for it, due to the R&D that goes into guaranteeing compatibility, labor costs, tech support... At least, that's the theory, I built my own so I wouldn't know. If you don't want the hassle, buy a tape machine.
