Very easy to build yourself, I have seen the ones you can buy and they do not compare to a home custom job.

you will need: wood, screws, copper pipe brackets things, varnish, daisy chain power splitter, and a PSU with suitable ohmage for powering all the pedals and some pedals.

then you just wap it all together as you can see below and its good to go, ripping through the effects loop.



There is space for one more I hear you say, that is true and thanks to ebay a mega bargain Liqua-Flange is on its way to plug that gap.
