Canned Noodles

Today I received a mid-2010 21.5in iMac from a friend of a family member. I replaced the old hard drive (per request of previous owner) and put it back together. I powered it up and didn't get a video output. It does chime, the hard drive spins up, and I think I can hear the fans, so that's kinda promising. It's a neat machine, so it would be nice to get working.

this CPU looks pretty neat
with the tapered corner it reminds me of a socket 478 CPU, but the ceramic under the IHS makes it look quite different
