Good case that don't cost much with a decent psu are rare even in the best of times. Got tired of junky modern cases that are mostly cheap plastic and some sorry excuse for metal. So I just made use of a hideous case from the 90s and put money into getting the best bang for buck psu.
You might not want that but just a thought. When it comes to the psu brand and model is every thing now days but even then you might get something that is just junk after all that is all what they make except for a few. :s
Rant: To many cases now days all look the same with poor taste and built almost as flimsy as the box they come in.
