It depends on the price. I mean, you could go and get the ASRock and then just get a cheap WiFi adapter. That's how mine is setup right now.
When it comes to stuff taking up more space, the integrated wifi is golden. I'm also a stickler about things that plug into front USB ports and cable management. A clean and neat appearance/environment enables for higher achievement. Price for a P8Z77-V Pro vs Extreme 9 (very nice board with intergrated wifi) is much less. We all have our standards
. Thank you for your input.
