I have a Compaq...and I must say, that compared to Dell...they at least TRY. I have a sort of custom box, with one screw to open it up. So you can clean inside and change stuff around. They left 2 spaces for extra memory, even though they gave me 1 gig. etc. Today, I was trying to clean a Dell of comparable age to my Compaq. The box is the most absurd I've ever seen it. In the end, I couldn't open it, without breaking the plastic.
Conclusion: Dell is CRAP.
