Seperate cooling of PSU in custom-built cases

[kloppe]

Since I'm too lazy to ever actually build a case myself, I thought I'd share this little idea with you. :)

What I've been thinking about is similar to the BTX-like PSU channels, only rotated 90 degrees along it's X axis.

A regular PSU duct/channel works great for fanned PSUs, but not very good at all for fanless ones (e.g. the Phantom, which is clearly designed to sit next to an exhaust fan). But what if you rotate the channel, and thus the PSU, by 90 degrees? Especially in the Phantom's case, it seems to me that the external fins are ideal for completely passive cooling at that orientation.

Some quick'n'dirty Sketchup work to illustrate what I mean:

Any comments?
