About the case being specifically designed for air cooling. I see on the product description and pretty much every review/unboxing talk about it's ability for water cooling. I'm actually now torn between the 540 and the new 750d, but think I'll stick with the 540 due to size.
There is a reason the case is called the Corsair Carbide Series Air 540. Check out Anandtech's review where Dustin digs into the cooling design.
"Corsair hit a lot of the right notes with the Carbide Air 540. For the first time they've produced a case that has excellent air cooling performance. This was pretty much the last issue I was having with their hardware, and it's largely been resolved here."
I think I'm gonna stick with pretty close to what I planned. I spend a lot of my free time either on my comp or gaming on console, so I see this as money well spent. Yes I am looking to save some money but have done tons of research, and would like to buy parts I won't have buyers remorse about. No I prolly won't notice a difference between part A or part B, but mentally I'll feel like I do.
When all is said and done I want a computer I'm gonna have no regrets about. I don't wanna be kicking myself a week later about not buying a certain part. I see no point in buying cheaper now to save for the next great thing. I've been a part of this never ending upgrade cycle before, and am gonna avoid it like the plague. Get the best I can now and be happy 🙂
You can certainly spend a lot of money trying to avoid an upgrade cycle, but you've picked an ineffective path towards that goal. Specifically, you're spending a lot of money on "gamer" parts (mobo, CLC, RAM) that exist only to separate you from your money and do not impact performance. If you really want to maintain high performance over the longest term possible, you should spend money where it matters: the GPUs. That's why I said you could cut other parts to get GTX 780 SLI right off the bat.
It's your money at the end of the day, but buying top end parts in an attempt to avoid an upgrade cycle is a fool's errand. You simply cannot buy a computer today that will run the games of 5 years from now at all max and high framerates. Your overall best bet from a longevity point of view is to make the changes I suggested but stick to a single GPU. Then you can use that money to upgrade the GPU in a few years to a much faster model.
