I seem to be the morning welcoming committe of one, so Hi!
There are numerous threads on the first page of this forum about cases. Select what intrests you. Then post about it with links. There are many here who have worked more cases than I have by a long shot.
Do not go for cheap on your PSU. About the best for price point are the PSUs with the
FSP Group branding, Forton/Sparkel come to mind. Antec PSU? Do a search of General Hardware Forum there was some stuff posted there several days ago that was not too complimentery. I have only used Forton, so I don't know.
My next PSU will be a Emacs/ZIPPY. No bells or whistels, just a very good unit and not that expensive.
Yes! Get a case w/o a PSU as the ones generally supplied with the case are substandard.
They meet the minimum requiorments, a PSU failure can take-out most of your system.
I'm not trying to instill fear but a decent PSU is just good insurance.
