Antec makes great cases. And while that one has fancy lights which I don't like (I want a case to sit quietly and discreetly out of the way so I can stay focused on my monitors), it has excellent build quality, lots of great fan options, washable air filters, USB ports up high so you don't have to get on hands and knees to see, variable speed fans, removable drive cages and more. With that case, I could live with the blue lights - and at least the top one can be turned off.
I am not into overclocking but apparently that CPU does well. Just understand, and to ensure you are aware of the consequences, in spite of what marketing weenies claim, overclocking voids the CPU warranty, as does using a 3rd party cooler. If you are okay with that, no problem.
ASUS is a great motherboard maker. Check the motherboard's webpage and you will see QVLs (qualified vendors list) for both CPUs and RAM that are compatible with that specific board. You must use a CPU from the list. For RAM, there are too many makers making too many RAM models for motherboard makers to test and list them all. So you can buy a brand not listed, you just need to make sure you buy RAM with specs that match RAM on the list.
Note too you can download the manuals for your components now and get familiar with the components before they arrive. Pay special attention to mounting the motherboard, and proper standoff positioning.
