Just checked it out, looks like a great start! When I did mine, power was not my main concern, as much as being compatible as a hackintosh. Not that you can't build a beast of a hackintosh, but I was more trying to replicate a Mac Mini. So I was just trying to scale everything down as much as possible, while still having a pretty sweet daily driver (that wasn't always on the verge of melting down).Here's what I did to get a small, cool form factor:
-Mini-ITX board (or smaller if possible). Put it on some posts, so it's not touching the "floor" of the case.
-Shortest CPU (replacement) fan possible. I used this one from Silverstone: http://www.amazon.com/gp/product/B003U6XZNU/ref=wms_ohs_product?ie=UTF8&psc=1
-Intel i5 w/ onboard graphics. NOTE: Graphics cards are really too tall to get in the case (which is why so many people have trouble closing it all the way). I am not gaming or editing, so the 1080p onboard graphics work well for this build!
-Mini-Box Pico PSU DC External power supply. These things are great! I doubted the potential power, but the 150Watt was enough to power the board, and the onboard graphics just fine. Do your math, and you may just be able to get away with one of these slick lil guys: http://www.mini-box.com/picoPSU-160-XT
-Laptop hard drive, instead of a desktop drive. They are just as good (if not more rugged), can stand more heat buildup, and perform just as well. I slipped one of these ventilated silicon covers on it (so that the metal drive does not make contact with the motherboard), then slid the drive underneath my motherboard. Cut a hole for the drive to "breath" (where the hole on the drive is), and maybe cut off the bottom of the silicon case to plug in: http://www.amazon.com/gp/product/B002GWF492/ref=wms_ohs_product?ie=UTF8&psc=1
-Micro USB Bluetooth dongle, plugged into rear motherboard usb port (an internal connection may work well too)
-WiFi Card. This is what I used my PCI slot for, since Hackintoshes don't have onboard wifi (even if the board does). It is actually the same card that would be in a laptop, but plugged into a PCI adaptor with external antennas.
laptop drive. Again, slim it down as much as possible, I bought a slimline samsung drive, and it works great!
-No way to get smaller RAM, so get as much as you can (I guess) in the same space. Try to one use one slot if you can (less space, less heat).
-Make your own grills! That's what I did (see above) using the extra cut out pieces from the case. Drilled a few holes and siliconed em on the inside. It looks better than open holes.Small and cool is the name of the game!!
