Just thought I'd mostly chime in because I'm looking to do a rack as well and would love to see what you end up with.
A couple thoughts though. I'm not sure how much money you'll save as it seems workable shelves can be had in the 100 dollar range. Costco is another place to check.
Some of the racks would need to be reinforced though.
I'd really think about what you want to do ahead of time tank wise. Think about what your goals are concerning whether you want to be space efficient or more aesthetics oriented, etc... Also, consider the livestock choice and what tanks sizes will be most appropriate. You very well may have considered all of these things already so I don't mean to sound like I'm teaching you something you already know. Just some things to contemplate in case you hadn't as I'm going through the same process.
I'm trying to decide on tank size and if I'll configure the tanks short side out or maybe a mix. This really comes into play with shelving unit depth as often times it seems to that in the 4 feet lengths the units are only 18" deep and you have to go even longer to get 24" deep shelves. I need to look around more and I'm sure more unique sizes can be had online somewhere. If you build you won't that issue.
I look forward to seeing how it goes for you and good luck!
Also, interested to see your filter choices, etc...
