If you can wait a few weeks I would suggest ordering a factory assembled panelboard which is usually quite a bit less expensive than ordering the individual components from your distributor and assembling them yourself. They can usually get you the can in a few days then will deliver the interior and front at a later time. The biggest savings ordering it factory assembled is the cost of the branch breakers. I have compared the prices of factory assembled to field assembled several times and the factory assembled is often about 50% less.
If this panel is for residential use where most of the circuits are going to be cable you might want to get the can with ko’s but if the circuits are going to be in raceways order it with out ko’s. If you use Square D the standard cans have ko’s on one end and are blank on the other end but you can specify otherwise.
