RESERVOIR development

[Jedda]

but I'd be even happier if I had a good small top/reservoir for my Laing. Preferably with some kind of decoupling/ mounting system that allows it to be mounted in a a 3.5" *or* 5.25" bay.

Kinda funny, with that picture just above your post.

The small holes you can see in the alphacool pump tops' side are for drive bay couplings and they have a small squarish res that combines with that top.
So it's out there. You've just got to track it down.
Unless your's is a D5, not DDC.
