I am thinking about getting me an iMac 5K but not really interested in overpaying for my RAM - can I access all 4 slots in the newest iMac 5K so I could buy the entry level with 8GB and then upgrade it to 32GB myself?

Yes, but make sure they are the same frequency so there won't be any issues. (1867)
