Late reply but this is probably good information for lots of people anyways.
I've been ordering computers for my company in HK and started with local vendors. Then we found Dell and never switched back. The local stuff desktop and notebooks just don't compare. The quality of the cases, keyboards, ram, cpu, and everything are definately cheaper with Dell.
We haven't had any problems with Dell and the Dell's just plain run faster. To save money, the best way to go would be to order the Dell PC and get your Monitors and Windows Office/software at another vendor. All accessories like USB keys, printers, scanners etc... are cheaper if bought elsewhere. I go to Wanchai Computer center which is reasonably cheap and close to Central.
If you go with Dell, run this software to remove a lot of the spyware/adware installed and you will have a much faster running, booting, and more stable PC afterwards.

Oh. And if you get a notebook, get the Dual Core CPUs. It is really MUCH faster and definately worth the extra money.
