I am building a compact high-end gaming PC (mostly for mobility), and I had a few questions. Here are my current core components-
GTX 780
i5-4690K
Trident X 8GB 2400
ASUS Maximus VI Impact
650W PSU

I was planning on adding a simple water-cooling loop for the i5-4690K, and possibly the 780 in the future. How much clearance is there for the radiator+25mm fans, if I am also going to use a 5.25 Bay Reservoir? Is there enough for a 30mm rad, or will I need to buy a smaller one? I would like to know so i can properly plan my loop.
 
Solution
I've never actually seen a definitive figure on how much radiator clearance it has, possibly because it'll vary depending on the motherboard you pick. Any board with a clearer "top" edge might allow a small overlap which would extend the clearance by a couple of mm. I've seen a figure of 55mm listed somewhere but it's a little unclear as to the context.
With the Impact (or similar) you can fit a H100i with minimal room to spare. Given that's around 52mm thick, I doubt you can really go much bigger without getting creative with mods etc.

There are plenty of builds doing a similar thing to this though. Corsair did their own version "God lives underwater" which shows you some of the pitfalls. It uses a bay res and a 30mm rad.

I think overall the 250D is a tricky prospect for a custom loop as almost every component is hugely limited in selection and the final product always ends up a bit messy. Great challenge though.




Er, that's not what he is asking, and all of that is wrong.

Still wrong.

A reference GTX780 is 267mm long. The 250D takes up to 290mm cards (so most things) so that's likely to cover any GTX780 as off the top of my head the longest is the Gigabyte Windforce at 287mm.

Not all 240mm radiators will fit. It has the mounting location on the side but not the depth. This is what he is asking about.
