List only client computer objects in AD

I want to get all client-only computer objects from AD, I mean, Windows Clients machines. I am using the sample code from this thread, but I would like to know how I can filter servers out.

Here's my code: 

class Program
    {
        public static List<string> GetComputers()
        {
            List<string> ComputerNames = new List<string>();

            DirectoryEntry dirEntry = new DirectoryEntry("LDAP://neuventus.local");
            DirectorySearcher mySearcher = new DirectorySearcher(dirEntry);
            mySearcher.Filter = ("(objectClass=computer)");
            mySearcher.SizeLimit = int.MaxValue;
            mySearcher.PageSize = int.MaxValue;

            foreach (SearchResult resEnt in mySearcher.FindAll())
            {

                string ComputerName = resEnt.GetDirectoryEntry().Name;
                if (ComputerName.StartsWith("CN="))
                    ComputerName = ComputerName.Remove(0, "CN=".Length);
                ComputerNames.Add(ComputerName);
            }

            mySearcher.Dispose();
            dirEntry.Dispose();

            return ComputerNames;
        }


        static void Main(string[] args)
        {
            List<string> newList = GetComputers();

            newList.ForEach(Console.WriteLine);

            System.IO.File.WriteAllLines("C:\\SavedLists.txt", newList);


        }
    }

Can anyone help me?

Try adding an operatingSystem condition to your filter.

mySearcher.Filter = "(&(objectClass=computer)(!(operatingSystem=*server*)))";

Note that this will only work if the all your servers are running a server operating system with server in the name. Also assume that no client machines run a server operating system.
