I talked to Mike about making a stand. He said we'd need a router and all sorts of fancy stuff to basically make a beefy cabinet. lol. He's so cute when he's trying to show off... Did you have any fancy equipment or just a screwdriver?
You two are making this much harder than it needs to be!
Stands & sumps are very simple even for non-handy people like myself. You can do a simple stand out of 2x4's & just sheath it in some wall panels like these; you'll end up with a sturdy stand that will hold up well & will last while also looking very good. The whole project wouldn't take you too long to do either; you could easily get it built in a couple of hours, if that, and then do the stain/paint. As for the sump, I would get either that 40 breeder that's already ready to go or just do a baffle-less sump using some other aquarium (preferably the 55 gallon). Just remember that it's all fun & games until the power goes out and your sump overflows due to a lack of space for the extra water, so don't fill the sump up all the way & plan accordingly!
