noticed your Wii is also on Wii connect 24 mode - that may just damage it (hasn't been proven either way yet but i'm a bit dubious about that).
Also - you've had it a year? it seems well ventilated there, has it always been there. If so then thats not good.
I'm beginning to think the 360 may be outputting more heat / working harder when connected to HD TV's - has anyone had theirs RROd yet when well ventilated connectred to SD TV? Reason i'm asking is i've had mine a year now on a SD Tv and no problems but i'm gonna buy a HD Tv and just wondering if it's gonna effect it in any way.
