    Yeah, I see how that would work, but I'm more interested in a compact solution. I guess DIY isn't always pretty. Don't they sell single bay PCI-e enclosures of some sort with built in PSUs?

    edit: Other than the Vidock of course.

    this isn't exactly the best case to use an sli power supply but it does do the job relatively well. its compact and should fit neatly in a modified acrylic box from homedepot or lowes.

    thermaltake also makes something similar that doesn't require a molex and is a grounded 3 prong plug

    Hmmm, now I'm thinking about making my own little ViDock...what if I grabbed a cheap Shuttle PSU (http://www.censuspc.com/product-pr-77.html), maybe a 80mm LED fan, the PCI-e - ExpressCard Adapter, and something like an ATI 4870 (or whatever will fit in space/power) and then slap it all inside a small metal enclosure, drill some wholes for mounts and air flow...and I should be good to go, right?

    edit: Azu, practically read my mind.

    Engineering sample is pretty much like a beta, maybe you can order an ES. But your last resourse is to do what I drawn several posts back. but in theory it would work too...

    Shuttle PSU would be ideal, but those are expensive. Luckily I have a spare :) from my past experiences with Shuttle. It's 240W, more than enough.

    But ViciousXUSMC's find will work too, for $20.

    I'm very interested in this. I already have a PSU, an 8600 GT (no 6-pin required either), just need the expresscard and PCI-e adapter. Basically PE4 is same as PE2 but with 16x PCI-e then? A PCI 1x card could run games at lower res, kind of like what is in Asus N10J, and it's $30.

    I think I'll write them to see what it takes to get an engineering sample. Whole concern is what will expresscard adapter cost? If it's $100 then it's kind of a mute point. But my thinking is cost will be about $50. Could probably come up with a whole device for under $100.

    Well the PE2 is same thing at 1x PCIe for $30, so figure a bit more. Maybe eventually for $40, but still cheap.

    And actually if you don't need a 6-pin PCIe power plug, then you could get away with a 1U power supply (like HD4670 or 9500 GT)

    wow guys this is quite cool by looking at what all you are suggesting should work hypothetically the only thing i think you need to be careful about is the psu shortening out a component or over surging something. i think someone needs to volunteer doing this. If this works will prolly see this from china in like 2 weeks a cheap kit.

    From a retail cost perspective as a current "builders kit" I see the ExpressCard device with PCIe 16x adapter for $50 + PSU $25 + Case $25 = $100. Quite reasonable if you ask me.
