I mounted a side fan on the side panel and used a fan splitter on the rear and side fans so what you see is the plug empty for on the splitter for the side fan.
Afraid the case fans are white led they don't change colour.
No I linked them to the the cooler master rgb controller, front and bottom fans to the first channel and the rear and top fans to the second channel and the cpu cooler to the third and the led strip the fourth channels so that there is a split in the colours so the kids can change them if they want..I didn't use the rgb header on the board at all.
Evil uncle first gave them 1 present and told them they had to share it and it was for house work! They didn't really like that idea and didn't twig they had a comu cleaner air duster for cleaning the computers when they looked at it. https://www.amazon.co.uk/gp/product/B073F9NY1X/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
They both like Assassins Creed games and Star Wars games that they've played on my computer, but I gave them £50 each gift vouchers for steam to get what they want.
The mounting bracket had two reasons 1 kept the wiring to 1 sata cable as the triple plug does the rgb controller, DVD drive and HDD drive and 2 lets me fit the bottom fan in the case.
