I built my stand for my first tank and 4-5 years later I’m still happy with it. I went the unconventional way and used leveling casters for the feet. They are awesome and sure help when needed.
I also found a quartzite countertop remnant for my top. It cost about $50. That thing will never ever bow. I also got it bigger than the tank on sides and front. It really is nice when doing maintenance or frag work.
Im sure your skins and doors will be top notch but those are just some things I did.
I even went and used the leveling castors on my 180 gallon upgrade 3 years ago. I highly recommend them.
