Possible Suggestion/Solution #1

CaseComment is separate object in salesforce. So I suggest you use either standard controller extension or custom controller.

But If you want or have to use only standard controller here is some code:

<apex:page standardController="Case">
   <apex:form>
       <apex:repeat value="{!Case.CaseComments}" var = "cc">
           <apex:inputField value="{!cc.CommentBody}" label="Internal Comments" />
       </apex:repeat>
   </apex:form>
</apex:page>

Possible Suggestion/Solution #2

<apex:inputField> can only be used with SObject fields as per the documentation. Your Case.CaseComments returning a List. So you have to iterate through the list to access child fields.

<apex:repeat value="{!Case.CaseComments}" var = "child">
    <apex:inputField value="{!child.CommentBody}" label="Internal Comments" />
</apex:repeat>

NOTE: Make sure to check the child relationship name in the WSDL for safe side.
