new build walkthrough

well half of the stuff I ordered from newegg arrived today but because of the holiday the other half will be arriving on tuesday (unless UPS will allow me to pick up the package from the local center myself on saturday. anyone know if they allow this?) I will then be building for the first time and would like to make sure that I do everything in the correct order. Here is what I plan to do but please correct me or feel free to add comments, tips, etc. First place the PSU into the case and plug in but do not turn on. Then attach the CPU and heatsink to the motherboard. Then place the motherboard into the case. (I have a Lian Li PC7 Plus - anyone have any experience with this case?) Then insert the RAM and the Video Card. Connect everything to the power supply and attempt to POST. If this all goes well then connect the hardrive, dvd drive, floppy drive. Attempt to POST again and then if everything goes smoothly, install windows and upgrade the BIOS. Is this correct?
