I think the VoomPC case uses the case similar to the DSM, and/or you could always just find a copper block that buts up against the case to wick away the heat...once you conformal coat the mobo (you have to tape off the cpu and RAM slots and stuff b4 spraying..thus you could bolt down the regular cpu fan and it wouldnt be a problem)

Let us know how it goes for you

Another good idea- I have a small mill, so could certainly prototype a heat sink that wedged against the top of the box.

My gut feel is that I don't need to coat the MB if I keep it enclosed, although I would not know for sure until systems started failing a year or two from now.

I think I will coat my expansion pack boards- They will be closer to the water, so in a harsher environment.

Thanks again-

Well I shelved this for a few weeks to let it ferment. I'm currently of the opinion that if I put a standard Mini-ITX board in an enclosed area, the fan on the heat sink would help circulate the heat in the case, which would help the fins on the outside of the case pull the heat out.

So I think that running a fan inside the closed case is better than no fan, as long as the fan does not fail.

So I'm looking at getting the Phylon 7f2WE16 board- It is a 1G VIA C7 board, with a small fan on it. The neat part is that I can add on 1-3 10/100 ports, or 3 1G ports for $42-$52. The Via PD6000 was my first choice, but it is end of lifed, and the replacements are not available yet.

I'd put it in the VoomPC case, and making a new sheet-metal end-cap that has my logo, and closes up the vent holes. Not sure if I'll use a thumb-drive, CF or HD for storage yet.

I plan to get one soon for testing- The last sticking point is if DSL would be happy running on that board.

VIA C7 1 GHz processor
VIA CN700 north bridge
VIA VT8237R south bridge

Any ideas?

Why don't you make your own case, like I did? ( http://www.louddata.com/minihog.html )There is a metal lunchbox sold at Walmart that is 7"x9". It's that exact size to fit a mini-itx board with space for cables and a small hard drive. ..

Can't get boxes like that where I live. I was looking all day today for biscuit tins, and too my annoyance they were all round! Has anyone else got suggestions for DIY casings, perhaps camera casings or
old vhs cases whatever? i have a C3 board crying for a home!

One of the choices I was looking at, that is also available almost everywhere, is one of those small lock-boxes. You know what I mean? It's the kind of small box with a handle on top and a lock in front that vendors use for cash at flea markets and such. They are made from faily heavy metal compared to the luchboxes. You can get them at any office supply store.
