Nice! That's really clean for a first time build. It's even cleaner than mine, and i've built several PCs. Not sure if it applies on that board, but some boards don't have x16 slots throughout, so you might want to move the GPU to the first slot to be safe. You can also check the link speed with GPU-Z. If it's 16x, leave it be, as it's in a good place.
What case is that? I like how it looks.
