T shirt was because I pre ordered from farnell.com. Have had it running this afternoon, had issues with power,has to be 5v so USB from pc won't do, HTC phone charger works a treat. HDMI cable, one I pulled from my onlive box didn't work, no image on screen but tv knew there was a signal as it switch to the correct hdmi input, but tried hdmi from out my media player and it worked. Also not 100% sure but think my sandisk sd card had issues as was class 2 8 gb, tried with a PNY class 4 and no issues. Pretty impressed with it so far, now just need to find an good use for it, build a case and make a rechargeable battery pack. It just doesn't fit in an altoid mint tin unlike the ybox2, but the website does have PDF of a box with all the holes in the right place that you print out and cut out of card, though mine got hot so might make it out of some sort of plastic or thin metal.
Give us a shout if you get stuck with yours and can't find an answer on the web site, though it is a good forum on there so doubt you'll need to.
The i7 rocks nicely at 4 ghz and is cooler than my old 920 DO clocked to 3.6 ghz.
Had a panic moment fitting it though, removed the corsair h50 cooler and cleaned it all up with some proper chemicals I'd bought. Dropped the 980x, bounced off my desk onto the floor as I went to seat it, felt like crying and was convinced it wouldn't work. Put some arctic silver paste on, re sat the cooler and fired it up. Pc just kept powering on and off, not posting. Thought it was a goner. Powered it off left it a bit and tried again, still nothing. Re seated all the ram and cleared CMOS, and bingo worked a treat. Got straight into bios to sort ram voltages and it booted straight into windows no hassle, then used easy tune 6 and did the one click over clock to medium 4ghz, no issues and it flys. Very happy with it.
Tomorrow will be cloning my momentus xt hybrid drive for the corsair m4 512gb ssd. Should be a leviathan after that!
