Whats really nice is the front fans are blowing in and the rear fans are blowing out
That's how it should be. If not, then someone goofed when installing. You generally want front-to-back flow through the case. That said, many cases are now coming with "blowhole" fans - with large (120 - 140mm) to monster (200mm or larger) fans on the top of the case exhausting heat out, taking advantage of the "heat rises" principle of thermal-dynamics.
I am building a new computer for my son using an entry-level (for Antec)
Antec One. It comes with a 120mm exhaust fan in back, and one 120mm exhaust fan on top. But it also provides the option with space (and mounting holes) to add 3 more fans; one 120mm intake in front, one 120 or 140mm intake fan on the bottom, and one 120mm intake fan on the side panel (but I don't like side panel fans, so that one does not interest me). I tend to really like Antec cases because they typically are very sturdy, "true" (exactly 90° bends) and they typically provide lots of fan support - even in their budget models like this one. Plus, Antec fans are of good design using precision ball or fluid bearings - which means they are very quiet and vibration free. And many Antecs have removable, washable filters - something I insist on for my own computers because I don't like breaking them down to lug outside for cleaning.
Plus, they don't have fancy front panels and most come without flashy lights - which do nothing for performance, consume power, add some heat and do nothing for performance (worth repeating). I like my cases to sit quietly and discreetly off to the side and not draw attention to themselves. After all, I want to pay attention to what's happening on my monitors, not the case.
