I will be working hard over summer so I can buy me some of that LGA 2011 goodness when it arrives! I hope they have the same look as the SB boards!
I hope not My antec 1200 is pretty large, any weighs almost 5 stone! Any larger and it will collapse in on itself and form a black hole If I run out of room I may consider one of those loops in a tiny case builds though!
120mm case fans? Try 2m!
Any good quality memory like Mushkin, Corsair, Crucial, etc. Specifically any memory that is compatible with the X58 boards should be ok.
