Final update.
After some more MDF cutting making a removable front panel the whole unit was painted. First two layers of MDF primer, then two layers of matt black acrylic and finally a bit of magic (drybrushing with brass and pewter colored paint).
It is quite easy to make a ripple in aluminium mesh, just cut out a small piece with a wire snip and then bend the sharp edges inwards.
Project Tranquillity is done!
For those of you thinking cooling will be an issue, trust me, the nine fans in the PSUs generate a nice little storm across the case. You can also see the short mains leads that has been custom made to keep the wire mess to a minimum.
The management network has been installed and another 10-15 cross-over cables will be added later. The red power buttons are illuminated and act as power LEDs.
And finally, everything assembled and ready to be used.
