I have to say I just bought the x-nav with the 500W psu and I am really happy. I was a little uncomfortable paying the extra $$ but it's worth it. Plenty of room, looks great - was kind of a pain to put together - but otherwise, its very nice. It doesn't come with 5 80mm fans.. it comes with 4 - 2 in the back, 1 up top, and and 1 in the front. The 5th fan is a 120mm on the side. You can adjust the fan speeds collectively, not seperately. But even when I had all 5 on full AND another 80mm I put in myself, it was still relatively quiet.
Either download and print the manual before you begin the transfer of items, or have another computer available to read the manual online as it didn't come with one and you will need it.
