Need help choosing a cooling system to overclock my i5 4670k. Must fit inside my Rosewill Line Glow Case

Hello folks. I am working on overclocking my CPU and am looking for after market cooling options, that fit in the Rosewill Line Glow.

Here are my specs, Pics included showing the space I'm working with. --- http:// ---


i5 4670k (currently OC'd at 4.0 with stock cooler, trying to go higher, hence this thread)
MSI GD65 Gaming Mobo
Nvidia 770 4gb
8 gb Corsair Vengeance Pro
800 Watt Thermaltake PSU
Samsung Evo 840 SSD 250gb
Western Digital traditional HDD 250gb
Rosewill Line Glow Mid ATX
Windows 8.1 Ultimate


That said I would like to buy either a liquid or air cooled after market CPU cooler but like I also said, I have the Rosewill Line Glow and it is limited on space it seems. I was looking into the these: ][url=http://techreport.com/news/23844/corsair-adds-new-h100i-h80i-liquid-coolers]http://.[/url]
I'm pretty certain the combo of the large radiator with the dual fans would run into mounting issues with my mobo heatsinks. The smaller one I may be able to mount to the back of the case opposed to the top like the dual fan radiator. There is also an option to mount that one on the side of the case but I worry the 770 might not allow room. The small corsair might be my best bet with the radiator on the outside of the case but I'm just thinking out loud.

So I have a few questions; Can I mount a radiator outside of the case? Should I, I should say. Are there coolers I can get that will fit this build? Perhaps the single fan, small radiator corsair settup. But then would that be an inefficient at cooling? Could I mount the radiator outside of the case on the top? I'd rather not do things like that but I want to try and push to 4.6 GHZ, maybe even 4.8.

I am also aware of some air coolers like the http://. A couple concerns with this one. It is cheap which is cool for my wallet but will it cool effectively. It also takes up a lot of room but in a different spot than the radiator for liquid cool would so that might work. However, I believe I read where a guy bought this and it wouldn't work in his Line Glow case.

TLDR;
I need a cooling option that will get me 4.6ghz or at least close, max price being 150 bucks that would fit in my current Line Glow Rosewill case and not rub against my MOBO heatsinks which seemed to be placed in the worst spot for top fans. Already had to shave down a stock case fan for it to fit. Advice on where to sit what or move anything to make room for cooling options is also appreciated.

Any help would be great! Thanks ahead of time.

P.S.
Just thought of something.... Could I put the radiator and fans in the spot at the front where all the hard drives would go?

If you've read this far, thank you. Any advice is appreciated and I'm anxious to hear what this community feels about this.

I like how you wrapped your Sata cables around the PSU cables, clever space saving solution. Why would you never buy another Rosewill again? I'm not on cloud nine with my Rosewil or anything but for 50 bucks it wasn't bad. Came with 4 fans which was a huge selling point for me. I just need a full tower.
