The mother board is a micro-ATX. It says the socket is an LGA 1155.
Can it take, for example, an 1150 as well, or does it have to have an 1155 processor? (I don't know enough about this to know how exacting the specs are.)
Generally speaking, sockets are not cross-compatible, although there are exceptions. In my experience, those exceptions are more likely found in the AMD lines than Intel. In your case, 1155 and 1150 are not compatible with each other; a CPU made for one will not work in the other.
Find the model number of your motherboard & find the current CPU list on the manufacturer's website or in the owner's manual. Occasionally you may get lucky and a few faster models of CPU in the same family may be released after the CPU list was finalized, but even then you have to be careful as they may draw more current than your specific mobo can supply or the BIOS may not be set up to correctly initialize anything outside the list. Dell especially likes to use that last trick to limit the compatible CPU's to a very limited set.
