LOL, many people I know have and are happy with their hp computers though. I myself have recommended these to people for a long time, and have personally bought for them. No complaints yet, knock on wood.
But it's all laptops though, those bought at amazon or at the dealers here, so no custom config AFAIK.

I was planning to buy an HP DV8T Quad Edition myself (after wanting a macbook pro 13, but after some consideration I found the dv8t which better suits my immediate needs at a pretty good price). Of course I'm gonna go ahead and buy it anyway, as soon as I find out if the caddy for the second hd ships with it when you buy the stock config.
