Will this fit a Dell Studio Slim 540s?

I think it is specifically designed for a Rosewill R-379-M case.

Will this fit a Vostro 200 (the skinny model)?

Hi, Does the case manual not specify ATX, TFX, Mini-ATX, etc.? Since the model you mentioned says 'TFX' in the name, it may or may not fit. If you go to the Newegg main page and search for 'Vostro 200 power supply' you'll see that Dell offers genuine replacement power supplies for that case for the cost of half of one hundred. (Since you can't mention prices here) Although that's about fifteen more than the Rosewill one you mentioned.

vostro 220 will work?

quiet and words fine with AMD 4 core CPU. Just make sure the dimensions fits your case
