I would offer that for most folks there is "good" and "bad" noise, or more aesthetically pleasing noise anyway. When I was shooting with the K100Ds I was almost obsessed with removing noise. But I really disliked that camera's noise as it consisted mainly of repeated coloured streaky stripe patterns. It's the clearly noticed pattern that makes it so objectionable. Even converting to B&W will not hide it. It's just fugly.
The K20D (and newer models I believe) produce more film-like noise, ie quite pattern-free. If you process a noisy K20D image in Lightroom you can decide how much to trade-off that noise against relative sharpness. At high ISOs (3200) objectionable colour noise starts to appear but is removed completely by Lr's NR filter. Just crank it to 100 and you're good. BTW, if I had taken another shot of this on a tripod, you'd see just how shaky and blurred it is. This was hand-held at 1/40th sec. A K20D with the DA* 50-135 on it is a pretty heavy thing to hold steady at the best of times. :) Thanks, Walt!
