Well, with the modern "hook" system it has been quite manageable, however, with the sides held together by little cam things rather than big self tappers and the whole cabinet hanging on two little "hooks" im looking at them nervously! I'm putting a couple of those screws you use for window frames down near the bottom to add a bit of extra stability but it doesnt seem as solid as the old rawlbolts the the previous ones were bolted to in all four corners, even if its easier.
