Aluminum or steel box - your choice! My machine is all steel box section, welded, including the gantry (which is relatively uncommon). I also used a fair bit of 20mm aluminum plate for brackets, mounting plates, etc. I wrote it up - have a look at "AVOR". However, many excellent machines have been built from aluminum extrusion. My choice was influenced by having a MIG welder and small angle grinder. The thing that would have helped was a decent saw for accurate cutting; a hand-held angle grinder is not really good enough. Same goes for using extrusion, which arguably needs even more accurate cutting - an angle grinder and welder can create and recover from a surprising number of small errors (don't ask me how I know...)
