CM690 II Advanced bottom-mounted radiator

Has anyone here actually mounted a 240mm radiator in the designated space at the bottom of this case? I have the case, have the rad, but the mounting holes are too far apart (it's like they're for a 280mm rad, except a 280mm rad is too long to fit - the case feet get in the way). The only way that I can see of doing it is to screw the 240mm rad directly to the grill. This is less than ideal, and would mean using washers - as well as not being able to use the included dust filter.

Anyone have any thoughts?

I didnt try to fit a rad, but I did try and line up some fans, but I remember running into issues with the fan holes too. I never really looked into it that much and thought it was me rather then the case.

It's kind of annoying because all the reviews were saying that the case supports a bottom-mounted radiator without any modding. It's like they just regurgitated Cooler Master promo without checking it.

I have seen a lot of CM-690s with dual rads in (one at top and one bottom) so it must be possible...

That's good news chronic. Can you explain how you did it?

What radiator do you have and what PSU do you have, there is a limited amount of space in that case so you need a relatively small 240 rad, the EK one seems to be popular in that case. But if you want a top radiator then probably you are limited to a Swiftech MCR220 because of height limitations (if you want to put one up there)

I've tried fitting a Phobya and a Thermochill (15mm fan spacing) 240mm radiator. The problem I have is not with the length of the radiator: it's the width. The top area has correct mounting holes for both 240 and 280 mm radiators, but the bottom area seems to only have mounting holes for a 280mm rad.
