Watercooling: Rad Mounts

[Netvyper]

I have a fairly small case; and im hoping to mount a 120.3 Rad above it.
It'll be a little unusual in that rather than drawing air out of the case, I want them suspended ~2cm from the top; and use the slightly cooler external air.

I reckon this could be done well by using slim bolts, with Perspex Tube Standoffs to mount the fans 2cm from the top of the case; and would look reasonable too.

What im working on now; is how to mount the rad & airspace above; the fans would then push the air through the rad & up away from the case.
So; are there any pre-fabbed standoffs/shrouds for such things? I've had a quick look but cant see any.
Also; i understand I should be pulling air through the rad; but does it really make that much difference?

Im hoping to get a friend who works in a schools D&T Department to create me a clear perspex box; which I can then mount to the top of the fans, my current unknown is how do I mount the rad to the top of this. Obviously it can be attached with self-tapping screws; but i'd rather use bolts so that the assembly can be fairly easily taken apart.

I wondered about using perspex tubing as a stand-off again, but im not sure if its possible to get the bolts into the radiator? So thats basically what Im asking; can i get sensible bolts in there or is it self tapping stuff only?

Oh, and if you've got any similar sort of setup I'd really appreciate pics/advice.

Rads tend to have self-tapping screw holes rather than holes through which you could put bolts with nuts but that said, there's no reason why you couldn't drill out those small holes for bolts. The problem is that the gap between the built-in mount points and the rad itself is usually very small; it would be hard to get any kind of bolt in there. It all depends really on how pristine you want this. I mounted a shroud onto a heatercore using nothing more clever than aluminium tape.

Look through the gallery to see how others have done stuff.

Aye, I browsed through the gallery last night; kept me up till 3am

That was my big concern; that I wouldn't be able to get bolts in between the rad & mountings. I ordered an "Alphacool NexXxos Extreme III 360mm Radiator " last night, along with D-Tek Fuzion, and an XSPC Bayres . The choice of radiator was purely because it uses standard M3 thread mounts; which means Im sure I can set it up correctly. There are eve pre-fabbed standoffs; which I cant link due to competition

Yip I've four of the pre-fabbed stand-offs for the Alphacool NexXxos II. I haven't used them because I decided to mount the rad in the top of my case, but they would have worked fine for fixing it to 120mm fitting on the back of the case.
