Enlarging the ME Molecular Assembly Chamber?

[Catts]

Out of curiosity, if I demolish a block what happens to the stored patterns?

Pattern providers function as chests for those patterns. If you destroy the provider block, the patterns will spill out everywhere. Otherwise, nothing will happen.

You can dismantle any block in the MAC safely except the pattern provider for the above reason. If you the inventory space then it's not a huge deal, just have some bags or chests on hand to store them while you move stuff around.

i recommend you place a couple diamond chests before planning a demolish on a MAC. and go straight for the pattern providers so you can space click all items into the chest. xD specially since each pattern provider stores twice as much patterns as you can carry.
