ok first off Im not sure where this should really go so dont have a great go at me, just move it. Im looking for a power button it is clear perspex and had a meal center, and I've seen it with a blue LED behind it, It looks really cool and I think It's look great on my Lian-Li. I've looked on these forums for ages, (I seen it ages ago) and tried google, but both with no luck. I'd like to know where I can buy one, UK please thanks .Keir.
I think you are looking for a Vandal Resistant switch, these are readily available (for a price) on http://www.maplin.co.uk they are really good, i use them myself
Something like the one bard made? http://forums.bit-tech.net/showthread.php?t=32590&page=1&highlight=switch
As Malcs said, the most common form of illuminated switch mentioned on these forums is the Illuminated Anti-Vandal switch. Maplin do one, but it costs £15. The other version is the original Bulgin switch, which is available in more styles and colours than Maplin sells. They have six distributors in the UK, including Farnell and RS. I found the switch here on Farnel - £12.42 excluding VAT. Finally, you can do as SteveyG suggested, and follow Bard's guide. This may be the best bet for the Lian-Li, as with a little extra effort, you can ensure that the front panel is still easily removable. I'd go with that - assuming you can get hold of some scraps of perspex (or acrylic, or plexiglass, or whatever...)
