Its an AIO, it should not need filling out from the box. It would defeat its purpose of being one if it didn't come pre-filled. Whatever the reason may be that you need to fill it, some PT Nuke(or similar) + distilled water should do.
Unless my Google-fu is screwed up, all reviews(1, 2) that I could find and this Newegg video points to the fact that it comes in one piece and pre-filled out of the box. The manual itself doesn't mention about it requiring any filling from the start.have u seen the product?
because if you have, you realize u can get the pump / drive solo.
which means no radiator... which means u need to fill it up after u get a radiator.

I understand that it is detachable/expandable/refillable but why does OP wants to fill it (assuming that its brand new)?
