Cases are largely a personal choice.
Bust your budget for one you love, you will be with it for a long time.
For most cases, my criteria would be two 120mm intake fans or better to provide adequate cooling.
Silverstone makes particularly nice cases. This looks to be a good one within your budget.

Do you really need a full sized motherboard and a huge case?
If not, look at a M-ATX motherboard and a smaller case like the Silverstone TJ-08e.
FWIW
I have become a bit jaded on the subject of haswell cooling for overclocking.
How high you can OC is firstly determined by your luck in the bin lottery.
I had high expectations from the Devil's canyon parts and their better thermals.
I found out that the thermals really do not matter unless, perhaps, you are a competitive overclocker.
Haswell runs quite cool, that is, until you raise the voltage past 1.25v or so.
Once you go past 1.3v, then you really do need very good cooling to keep stress loads under say 85c.
But, the consensus is that voltages higher than 1.30 are not a good thing for 24/7 usage.
I have been unable to find any official Intel recommendation on what is a safe vcore limit.
If you are an enthusiast, you can go higher.
Even if you can handle the heat, how much do you really need that extra multiplier from say 4.4 to 4.6?
My thought is that it is better to use the exotic cooling funds for a quieter and less expensive air cooler.
I suggest a good tower air cooler like noctua or phanteks with 140mm fans.
