Got one of those coming too. Small possibility it will fit it the bottom 
of this huge and old tiger direct tower.  Because the radiator for the 6 
core i5 is too tall, it hasn't had a side cover on it in years. If not, 
theres a 3 3.5" cage at the bottom of the stack I can stuff  with 2 
SSD's per bay slot. A hidey place, front cover is solid, but cooling 
might be a problem. If worse comes to worse I could shoe-goo a 120x15 to 
the side of the cage.

400 watter, presently runs dead cold. 5V line rated at 16A, probably not 
using half that now.
