Great, thank you for the info, how are the temperatures btw? Do I need an extra/bigger radiator to cool it, maybe fan too? When everything is done I'll probably will put it in a box and have it on the desk but I want to order everything together, that's why I'm asking if I'll need some more stuff.
Mine is sitting in the cupboard (doors closed) and it's fine there were no problem with overheating or anything similar (I've no HDD attached, I was trying to run a neutrino type hub)
I've bought this
copper heat sink, it's for the Pi and it was really easy to stick it onto the chips... it's about 2 EUR, free shipping, so it's not a big deal...
I think you should have some cooling because of the SATA HDD rather than the PI
