I would choose the trunking method of connecting switches over the daisy chain. The 5 switches can be trunked to the bottom basement switch, yielding less delay and providing a smoother convergence for STP. If you want redundant links, use a 2nd switch in the basement and apply 2nd links from the basement switch's to the floor switch's. You can either have seperate vlans or one flat vlan network, altho I'd choose a vlan per floor with 10bt to prevent broadcast from slowing the whole network down.

My biggest concern is the lack of redundancy in this design. If the basement switch goes out then the entire company is down. I have a Cat 4006 or 5500 on each of the floors. I utilize a daisy-chain approach with Gig Ethernet over fiber. This way if any one switch fails it'll only take out one floor. You'll want a lot of redundancy in your server room switch because if it goes out, then once again, your entire network is down.
