The Blu-ray makes sense. I still buy some things on BR as I like to own a few things physically just in case the internets goes down.I don't know when you're ever going to use a deprecated blu-ray player, or why you'd cheap out on the video card if it's a gaming PC, I think the case is ugly, that picture of the PSU isn't modular and I hope the one you bought is, and there's better RAM for the same price. Samsung 850 Pros are 3D VNAND, better in every way, and cheaper than corsair force (at least from the websites I surveyed).
Also if your PC is going to average 350W ideally you want a 700W PSU for peak efficiency.
The motherboard choice was great though, that's a very good motherboard! Some things to think about next time.
The z97 is worth keeping if it means keeping thick alloy chokes, capacitors, and better mosfets/voltage regulators.My suggestion as a veteran of five (yeah baby!!!) self-built rigs, is that you ditch the Z97 mobo and go for a H97 and get yourself an i5 instead of the i3. The reason for that is that the Z97 is for overclocking and that i3 CPU doesn't support overclocking.
All in all, a pretty great rig for the money. I like it!
XFX Radeon R9 280X 3GB: $260 before $30 rebate... it's better to invest more money into the GPU because it's the bigger bottleneck issue in terms of performance.
