Update:

I have started cutting back panel its not that easy as i would imagine.



and that how it looks half naked hehe



this is whats left


HDD Drive Cases are from my Silverstone TJ07 will find space in the bottom but have to cut little piece off coz they need to slide to a side to take them out from the case.



Like this


I will cut the rest of the back and then will start to mount mobo tray.
so more update soon.
