1. I think that is a nice case with lots of excellent large fan support.

And I am VERY HAPPY to see included dust filters - though from the review I read, I am not sure they are that easy to remove for washing. If you have to almost disassemble the case to remove the filters, that is not very convenient.
Also, note that pretty lights do nothing for performance, add some heat, consume some power and do nothing for performance (worth repeating). IMO, a case needs to sit quietly and discretely off to the side and NOT draw attention to itself. After all, I tend to pay attention to what's on my monitors and don't need any distractions from the case. I like the
Antec Three Hundred. It is reasonably priced, very well built, sturdy, "true" (exactly 90° bends), lots of large (120mm or larger) fan support, including a 140mm “blowhole” (top) fan. It is not flashy, plus it has removable, washable air filters. Or the
Antec Nine Hundred Two V3, with its monster, but silent 200mm "blowhole" (top) fan is hard to beat - even with its blue LEDs.
Also, Antec's fans are excellent so you would not need to buy any extra fans. But to that, that Sentey case has lots of fans, you don't to buy any more. However, that case includes two 80mm fans. Note for 80mm fans to move a lot of air, they have to spin at a much higher RPM than 120mm or larger fans. That means they WILL create more fan noise.
2. I like Corsair PSUs. But more importantly, WTG for selecting a 80-Plus certified PSU. To achieve 80-Plus certification the PSU MUST provide a fairly linear (flat) efficiency across a wide range of loads - as seen in computers (between idle and pushed). And it takes a good design and better quality (tighter tolerances) components to achieve a linear efficiency.
3. If more upgrade options in the future (including PCIe 3.0) are desired (and they should be IMO) I would go with the 3570.
4. Even if you don't care about preserving the 3-year warranty of your Intel (or AMD) CPU, it is
essential you fully understand, and accept the consequences that using an aftermarket cooler on your CPU
voids the warranty! And it also important you understand (in spite of
unfounded and incorrect rumors and comments to the contrary) both Intel and AMD provide
excellent coolers with their CPUs that are fully capable of providing adequate cooling even with mild to moderate overclocking. Remember, it is the case's responsibility to provide an adequate "flow" of cool air through the case and the CPU's HSF assembly need only toss the CPU's heat up into that flow.
5. Note that all motherboard makers provide QVLs (qualified vendors lists) for RAM and CPUs they have tested and verified are supported by their boards. You MUST ensure the CPU you select is on the list. However, there are too many RAM makers and model numbers for board makers to test them all so you MUST ensure any RAM you select matches the specification of listed RAM. Your QVLs are posted
here.
