Upgrading PC case-need suggestions!

Hello everyone,
as the title states I am looking to upgrade my pc case to something with better airflow and perhaps somewhat more quiet. My current setup is mostly compiled of:
CM k380(real budget case)
i5 4690
gigabyte r9 390

The cases I've been looking at are the following:
-CM Cosmos SE
-Fractal design define R5(windowed version)
-Phanteks enthoo pro

I personally would like to spend anywhere between $150-200 AUS. What I consider essential is air filters on all intakes and a side panel window. I would also like the possibility of adding a 240mm AIO cpu cooler in the future.

If anyone has had any experience with the above cases and would like to share some insight/opinions it'd be greatly appreciated.
 
Solution
I can chime in with positive reviews for the Fractal Design R5.

- Very sturdy construction
- Great cable management (this was a big deal for me)
- Modular internals so that you can fit just about anything you want inside of it (including liquid cooling)
- Air filter screens on all intake (front and bottom)
- Quiet, good noise reduction (though this wouldn't be quite as good if you get the window)
- Easy to clean & take side doors off when needed
- Side panel window option is available
- Additional built-in hubs for 2 SSD drives, great if you want to spend a bit more on 2 of those and ditch your HDD racks all together.

I'm building a new rig for a family member in a little while and will be using the R5. The only real downside I can...

Solution
I am heavily leaning towards the R5 but my only gripe with it is that the top vents aren't filtered when you remove the "modu vent" covers. I would love to get my hands on the Enthoo pro but quite unfortunately it is not available in Sydney AT ALL-I would have to order it from Melbourne, which would involve an additional $30+ for basic delivery plus running the risk of it being damaged in the process..
Thanks for your response hopefully others will chime in as well :)
 
No problem.

It's true the top vents aren't filtered on the R5, though if you plan on adding a liquid cooling solution that wouldn't be a problem in the long run since the top is used for outward exhaust for 240mm coolers.

Cheers, and good luck on your next build!
