Again, the AXP-140 is the biggest heatsink you'll get in there without modding, e.g. bending or cutting. I reckon you'd even be able to run a i7 2600 passively with that thing.
Forget the Zotac H55-ITX, it has the older H55 chipset and will only take socket 1156 CPUs, these are the older generation of Intel chips. The CPUs and motherboards you should be after are socket 1155, aka Sandy Bridge.
