I don't know if you saw the thread below:

In it, the OP blames blizzard b/c his Pentium 4 Northwood@2.8 GHz (an August 2002 model) is unable to run WoW.My system is a Pentium 4 2.81Mhz with 4G ram, NVidia 256 graphic card and 500g Hard drive running at 7200rpm. Not an old outdated system and can even run Windows 7. Not 10 year old tech by any means.
Now, it just so happens and my work laptop is a Toshiba S1950-801, Pentium 4 Northwood@2.8 GHz, Nvidia GeForce4 460 Go 64Mb AGP GPU, 2GB DDR1 RAM @333MHz, Intel i845PE Brookdale Chipset.
Proof:
Out of curiosity, I installed WoW on my laptop (it runs a modern 500GB WD HDD) and logged in to check on the OP's WoW experience.
Now, this laptop was the first laptop I played WoW on back in December 2005. From what I recall, it had trouble running WoW Vanilla at resolutions over 1024X768.
Here's the results: My laptop is only good for posting auctions. Trying to do anything else is laggy, and normal gameplay is very laggy. I can understand the OP's frustration, hahaha.
I didn't test it at 800X600 or 640X480 though. Might work somewhat better at these resolutions.
So, what is the oldest PC you have successfully managed to run WoW on? "Successfully" means that you are able to at least level up and do dailies without lag at or above 20 FPS. :-)
