Ok, so have done a little more work on the hard drives and received more shiny packages in the mail so I thought I would give you a little update
First for the Hard drives... I didnt like the way all the cords stuck out into the visible part of the case, so I modified the sythe hard drive mounts to turn them backwards so i could route the cables through a new hole in the back of the case.
(please excuse the quality of some of the pics, they are from my phone in a work environment)
So first I had to drill new holes in the mounts so I could push them forward into the case, and make room for the front fan.
Testing for fit
Then i had to cut them down to size because they were bumping into the front fans and making it hard for me to mount them both at the same time.
Here are the fans with filters attached and one of the modified HD mounts
And here is the finished product
And the hole going into the back of the case.
They are pushed out kinda far... but no cords!!!
They are completely invisible with the fan mounted in front
