Well, I swiped a file across the sides of this ITX PSU's PCB for a while and now it fits inside the IIsi PSU's sheet metal. It actually fits between the side rails of the lid, but I'm not going to mount it that high in the donor box.
I'm planning to use 1/4' -1/2" standoffs from the lid, or the equivalent height standoffs from the base of the IIsi PSU Can. This will allow an airway from the top vent, back across the "bottom" of the ITX PCB, down into the main section of the IIsi PSU Box near the back, where it will be sucked through and out of the case in the front by sheet metal ductwork leading to a good sized fan mounted underneath the FDD and blowing the hot air from the ducting out the bottom of the case through vanes directing it to the right.
The stock fan will be reversed, pulling more hot air from the case proper and I'll be replacing the speaker with another fan pulling air into the case through vanes set to draw it from the left side of the case. Ductwork from this fan will direct cool air around and over theHDD ro cool it and the Rocket's HeatSink RAM etc. and then it will pass back out the reversed stock fan. Some of the intake fan's air supply may be drawn in from the back of the Subterranean PDS Card expansion area, possibly all of it, cooling those cards mounted under the MoBo as well.
Dunno, gotta do some ductwork calculations once I get the sizes of all the holes, ducts, fans and the directional change radii to get the pressure losses dialed in. Mostly I've done this stuff for Dust Collection Systems with 4" - 8" diameter ducts . . .
. . . this is just a bit on the small side! :
Good thing my local lil' bro (the ME) does this kind of thing in blade servers for a living . . . maybe he'll humor me by taking a look at the cooling plan.
A Q630 type speaker jammed into the front somewhere should give a lot better base response for the custom countdown startup chime . . .
. . . followed by the much missed WHOOOOSH!!!!!!!!!!!!! of the Radius Rocket's Launch. :approve:
