[IMAGE]  here’s my customized 660 lol evga water cooler 12 gb ram pentium g2030 to i5 3570k (yes boost clock works fine) 4 gb 1650 OC gpu  One tiny problem - our tv is my 3rd display and typically after work rather than sit at a desk id like to play games from the bed on the TV, however the wire running across the bed has been annoying in the past, Is there any upgrade for the mobo internal wifi card slot that would support bluetooth for a ps4/ nintendo switch controller? (All but one of my front usb ports are in use) Thanks!
