This is just to satisfy my curiosity, thanks

1- Any pros/cons of a LGA 2011 over a 1155 ?

2- E-ATX boards, do they fit after- market fans,heatsinks ( cpu) better then a standard ATX ?

    Presumably you mean LGA 2011 for a Sandy Bridge-E system and LGA 1155 for an Ivy Bridge system.  The major differences:

    1)  Ivy Bridge has slightly better per-core performance than Sandy Bridge-E.

    2)  You can get up to six processor cores with Sandy Bridge-E (but this is very expensive), as compared to four for Ivy Bridge.

    3)  Sandy Bridge-E has a chipset that can do two PCI Express 3.0 x16 slots at once, as compared to one x16 or two x8 slots for Ivy Bridge, which could matter for a quad CrossFireX or quad SLI setup, but will only infrequently amount to more than a rounding error for an ordinary two card CrossFire or SLI setup, and doesn't matter at all for a single card.

    4)  Sandy Bridge-E has four memory channels, as compared to two for Ivy Bridge.  This means that you reasonably (i.e., with 8 GB modules) get up to 64 GB of system memory with Sandy Bridge-E, as compared to 32 GB for Ivy Bridge.  It also means that Sandy Bridge-E has more memory bandwidth, though this generally won't matter unless you're trying to feed a GPU from system memory.

    5)  Ivy Bridge has integrated graphics and Sandy Bridge-E doesn't.

    6)  Ivy Bridge has considerably better performance per watt.

    6)  Sandy Bridge-E is a lot more expensive.

    For gaming use, there's no real reason to get Sandy Bridge-E over Ivy Bridge.
