It's false economy to cheap-out on a system PS.would like a new case, psu, and fans. any advice on compoments that are fairly inexpensive?
Your thread title says you want "quiet components".
"Quiet" and "inexpensive" tend to not go together, particularly for cases, fans, and power supplies--not to mention that each term means different things to different people.
I'd at least be sure the case used 120mm or larger fan mounts.
Indeed, there are a few components that you can go "cheap" on and be safe but a PSU is not one of them. I third the recommendation of the SeaSonic. Do you have a budget for the rest of the components? Personally I'm a big fan of the Cougar CF-V12HP fans, very good air movement while being whisper quiet.
