do you have this two components?
on what are you relying?
what about the ninja mini?
I own a Scythe Ninja and Ninja Mini (desktop and HTPC, respectively). My brother owns the LC17 and IIRC the internal dimension from processor die to top of case is 150mm. The Ninja Mini will fit just fine in the LC17 since it fits (perfectly) in my Antec NSK2480 (which is much smaller internally).
Good question. Will the Ninja 2 fit in an Antec 900 (with or without the side fan)?
Yes, easily. But don't count on adding the optional 120mm fan to the side panel (i.e. will not work). My dad has the 900 with a TRU and it would only work with the cooler in the horizontal position with the fan on top blowing up toward the Big Boy fan. Since the Ninja 2 has a larger footprint than the TRU, it will interfere with the side fan in every orientation.
