DIY 400w SON/MBI gearbox

Was browsing eBay and I came across these enclosures and I quite liked the look of them.
The reminded me of lab equipment from the 70's and 80's, especially old Tektronix oscilloscopes so I decided to get one and put some gear that I had lying around doing nothing.
I already have a commercial 400w SON gearbox but I was bored and decided to build my own in it.
I quite like the retro look and it sounds really awesome when you first fire it up but it quietens right down to almost silent as the lamp runs up.
The frame is plastic with metal support brackets and the panels are steel.
