If you want to buy computer hardware, stay away from factories... If you have the guts to go there, they most of the time will ask you "how many 40 feet containers do you want?"-kind of question. Many computer chips made in Taiwan - at least the best ones are, others - Made in China. Motherboards, Graphic Cards, Sound cards, the finished products are mostly from China (many manufacturers manufacture their products in China, cheaper they say). Go to your favorite (r)etailers, buy your computer hardware there.
Best bang for the Buck (BBftB) is different for different people, so it might be BBftB for you, but not for those corporate entities, or those CAD/CAM guys. So, buy your favorite components from your favorite (r)etailers, and make sure you get the full warranty support off them.
