Thanks a lot for your reply, good to know that I can save some money on the PSU. I used the psu calculator from outervision btw. I'll skip the GPU cooler for now.
I'll be sure to check out the guide thoroughly. I took a quick look at the diagrams, if I want to light up the front and top panels, I'm going to need a 2nd commander pro right?
And as far as I can see, my motherboard has 1 USB 3.0 and 1 F_USB. Is that sufficient? Sorry for all the beginner questions, but I might as well ask the experts to learn faster.
