xbox 360 serious question can you help me???

hey, i used to have a 360 then had to sell it "money issues"

now i have sorted them i resently have percused a 360, its a preowned one but in very good condition it seems to be rather new as it has the hdmi port ant the back and its manufacuring date it like the 28 of october i just wondered what type of deigin it is .... as in is it falcon or so on est...... i dont think its falcon as the power brick watts is too high for it to be

please help if ne1 knows anything, cheers

i have its like 200 summat but i got told as it has the hdmi port it should have a fairly new one which is ment to cause less problems as in the rrod i just wondered if anyone has anyidea what one it has? i know the first batch of 360s had the xeon
