Whoa whoa whoa... I didn't mean to offend. And this is NOT about race, so don't freak out.
My point is: it's hard sometimes when you are talking on a support line and you just want to ask somebody a question about some spec/upgrade on your system, but they really have no clue (and can't even look it up in the documentation). And it makes it HARDER sometimes when there is a language/accent barrier.
There's the real problem for the PC geek and buying someone else's box. Having been a programmer for a customer service outsourcing company, I can tell you that the average call service rep has about a week's worth of training and is reading off a script. You're not talking to some A+ certified technician, and it's doubtful you'll be talking to anyone who knows more than you do, particularly if you're an enthusiast.
Toss in a language barrier, regardless of how big that barrier may be, and an already frustrating thing becomes moreso. You don't call tech support because things are working fine, only when things are borked. So the borkage alone has you angry and adversarial, and now some poor rep in a foreign country is being taken to task not only because their script is inadequate for your needs, but because the barrier exists. It's natural to become even more frustrated, as you started off with very little patience anyway.
So again, the home build makes more sense than buying pre-built. With a homebuild, you know every last bolt, nut, and capacitor in your rig. You have manuals for every last part. You did research to buy what you wanted, and you spent the time to understand how things work. And chances are, you came here and found out that a few thousand DYI PC builder geeks is way better tech support for free than anything you'll pay Dell or anyone else for.
Tech support reps could be next door, but they only go as far as the script takes them. I had a malware issue once that wrecked my Internet connectivity, and even the geeks at Micro$oft were out of their league. But a few visits to this and several other forums, plus some sleuth work on my own, and I called Micro$oft back to tell them what to add to their scripts should anyone else call with my problem. Once you go open source for any one thing concerning your PC, you'll find that open source rules, especially where building and fixing a rig is concerned.
