Update #14 - 24/05/2010
Got a new toy - Canon EFS 60mm f2.8 Macro!
I remade all the hard drive trays - I wasn't happy with the original design and I also realised there would be masses of vibration.
To solve the vibration issues all the holes have rubber grommets in them (this also elevates the hard drives meaning they don't actually rest on the acrylic at all and the screws that go into them don't touch the acrylic either). I have also lined the edges of the base of the plates with neoprene. This creates a tight friction fit between the rails and the tray.
I'm hoping this should be enough!
Here is a 2.5" drive mounted on one of the trays.
The drive doesn't actually make direct contact with the acrylic.
And with a full size drive on.
Quick test fit - these are all just test drives so i can check dimensions etc.
Bought an SSD second hand a few weeks back. It died unfortunately so i sent it off for an RMA, got a brand new one back!
It's a Corsair Extreme 64GB (Indilinx Controller)
Tightening it onto a drive tray
Got some laser cutting by a friend. This is a plate i have had done to tidy up cable management and also mount the res on.
The use of these holes will all become clear!
Still got to cut out some holes in the mobo tray - the new Dremel I got back from repair was dead on arrival!
