Rubbery Stuff...



As part of my theme I wanted black rubber to separate and accent some of the chrome work. So I cut up some grommets and made nice little rubber surrounds for my LED holders.



These were attached to the PSU cover.



Teeny matching rubber surrounds for the jack sockets were added and you can see from the picture of the inside of the bottom cover all the LEDs and jack sockets. The socket in the centre-rear will be wired up from my pump earth to the main earth in the PSU as the PCI pump relay card I will be using has no earth connection built in.

One thing I found was how carefully I had to plan where to place all of these things. Some test fitting was also required for things like avoiding jack plugs hitting capacitors, voltage indicator PCBs fitting in etc. There really wasn't much spare room inside the PSU once the fans were installed.



Taking a break I went on to assemble two voltage indicator kits from Dick Smith Electronics but replaced the dim LED that came with the kits with high brightness bicolour LEDs salvaged from a Sunbeam rheobus.



Note the power connector (formerly attached to the PSU internal fans) that will be reattached to the PSU internal fan power connections. The LED on the far right-hand circuit board has been sanded and filed to diffuse the light and make it look interestingly square-ish. I did this with most of the LEDs. With a planned total of over 70 LEDs for the case (including drive mods, etc), I wanted to cut out as much glare as possible whilst still having lots of blinking, glowing lights.



Here I wired up the LEDs to their jack sockets and wired up the pump earth connector. The pump earth connects directly to the PSU earth and I have used a heavier-duty wire.
