My knee jerk reaction is to wait on the reef tank.
1) Chemicals. fumes etc...While not a sure thing, cycling, populating and in general, getting a tank rolling with all the hecticness, dust, fumes, paint etc might be difficult at best.
2) I would suspect there may be many times when covering the tank would be necessary...not easy with lights and the like.
Perhaps, the framework and undertank setup and "guts" might be doable.
It may work fine, but if it were me, I'd take on one headache at a time.
