I'm looking for a new case to water cool for the first time. (My current case is a Cooler Master Storm Enforcer) I like the looks on both the 450D and 750D but I'm not sure which one to go with.

I found the 450D for sale for $170 and the 750D for $210. I was going to get the Phanteks Enthoo Luxe/Pro but couldn't find it anywhere so these two are probably my best option.

I'm currently leaning towards the 450D because of its cheaper price and smaller size. Would a custom loop fit in it? I'm not really planning on going SLI.
 
Solution
The 450D is a execulant case if your going to use something like a Corsair H100 but if your looking for a custom loop then you need more room like the 750D.

I'm planning on building a custom loop, thank you for the fast reply!

EDIT: If I were to go with the 450D would there be enough space for a reservoir and pump combo?

for the res/pump combo in a 450d yes if you get one that is the right size a 400mm res tube wont fit in the 450d but it will in the 750d something like ek's pump/res combo 140mm would same with bitspowers 150/80mm res with pump adapter

The thicker rads don't fit in the 450D but yes you could use the 5.25 bays for the combo.

How will I go about with mounting the radiator, will I have to drill some holes in the case?

I did some more research and read that the 750D "chokes" the front fans and it doesn't seem to have a bottom dust filter. Will these be an issue?

I'll probably just get the 750D though so thank you for the help!
