Besides the factor of knowledge, time is also one.
A friend of mine is a professional and she charges on a hourly basis. With her hourly rate, the time she spent on building a computer might well be spent on giving consultation and charging her clients enough to buy a new system.
Customer support is excellent. I recall an incident where her system had some problem. She called and a technician came to her home the next business day with a small suitcase. Inside the suitcase are almost all the new components (motherboard, ram sticks, video cards and power supply). He did the diagnosis onsite for half hour and finally replaced the PSU. (I was there all the time watching him.) Quite impressive.
This is interesting.
For the same system, it costs
$9600 NZD (~USD $8000) in NZ
$3999AUD (~USD $4300) in Australia
I price exactly the same system in Dell (China) website and it comes to USD $3900 equivalent.
I wonder how much the same system costs in Dell (US) website.
