I had a fish tank stand I was about to chuck out, its been in the shed for a while with the Cebora sitting underneath....Then I had a thought.
Fish tank stand as was

Added a top with a cutout for the Co2 bottle

Add the bottle
Next is add the castors which I got from Aldi at the weekend, four for £7.99

if the lack of strength is an issue, make the cross bar removable and bolted, add a couple of plates on the end of each end of the bit you've cut out, and drill and bolt back in place, then you have the best of both worlds, the strength and the access.
