I think I'm going to leave it open in the front. My current stand has doors and I'm tired of fighting them. Anybody else have a open stand?
Yep, hollow even.
Granted this particular setup has all hang on equipment, so no random pipes or wires hanging down in the void.
TroyReeF has a pretty good workaround on his 40g that may be something to think about if you want to hid equipment below. Instead of doors, you could run a velcro strip along the top of the opening and do a fabric curtain.
BTW, the stand is looking great!
