Depending on what cpu format you chose, the installation can vary. A socket cpu on the other hand is a little more of a caretaking process. Once it is in place, grab the lever and jolt it down. Memory isn't a brainer at all, just grab it and push it into a DIMM slot. When its in, push the white fasteners and it will lock it in.
Memory is known to be a bother to take out, but easy to put in.
Now that all the little stuff is in, it is time to actually put it in the case. This is a little tricky, but can be done easily if done right. Once your sure the mainboard can not possibly touch the case, fasten the screws, making sure none are loose. Now you have done all the hard work, most of the rest is just read the info, and do. There is only one place it can fit in, and only one way too, but if uncertain consult the manual for the right one.
