I wanna build a TCP/IP server that will be used by up to 100 concurrent clients, but still not sure how to get started.

And another Delphi library option would be synapse which provides a simple framework that can easily be extended. There is an IOCPPool demo available in the contributed files which may be of assistance.
Synapse is more of a framework of classes than a component library. There is a vibrant and active user community that is ready to support any challenges. I use this library in Delphi 2010 without any problems (although I use the latest development version from SVN).
Being as they are not components, it is very easy to use the classes in simple console applications or windows services.
