So, I've had this case since Nov 2014, my case being an nzxt s340 I like the look but its just too small and it was difficult to do good cable management... well for me it was and I just wanted to get your guys opinion on it; something that makes cable management easy, big enough so if I ever win the lottery I can fit 2GPU's on it and maybe liquid cooling on it, great airflow on it, and it has to have those filters that block dust from getting in it....Also if the price is not too high, sorry for being picky just broke :>
thanks!
Its of course a bit hard to recommend a case without knowing your exact taste.
Since case choice is basicly realy personal.
I personaly use a NZXT Phantom 530 like Wendell has done a review on.
Its allready an older case, but its realy nice, good build quality,
and more then enough space to work with.
THe only thing its lacking on is powersupply cover.
Thats a bit of a bummer.
But if you are handy, you could ofc make a psu cover yourself.
Phanteks Enthoo Pro is also a very nice case with plenty of space.
I really like my be quiet! Silent Base 800, but of course a month after I bought it be quiet! released the Silent Base 600. I would have preferred the 600 because the 800 is kind of big. The inside of the 800 and the 600 are the same, except the 800 comes with a 2nd removable drive bay.

Thermaltake Level-10GT owner here. It is a nice but expensive case.
I love personally love my Fractal R4 (though if I bought a fractal today it would be the R5 or S) but I prefer the Silent Base 800 or even 600 as @Cort_Byron said
Not a whole lot of details given other than "cheap"
Most really good (and practical) cases are around 100USD like: enthoo pro, define r5, H440
Would be better if we knew some other preferences of yours (i.e. minimalist/gamer design, window/no window, cube/tower, etc.)
If I wanted to get a new case it would definitely be by phanteks, either the evolve or pro. And price wise they are pretty damn competitive.
Cases are really a personal thing. I generally do not like to give advice on them because of that fact but Im sure people here could give you more pointers if you told us what you desired in a case
I personally have the Enthoo Primo. It is a monster of a case. Running two 360 rad, double bay res, 5.25 mounted fan controller, 3 3.5 HDDs, 1SSD, all with room to spare.
I love it, it is a huge case. May not be for everyone.
