How to create a enumerate list adding a custom prefix before each item number?

Question

I found this question Adding some common text to enumerated description lists to be the closest:

\documentclass{scrbook}
\usepackage{enumitem}
\newcounter{descriptcount}
\newlist{enumdescript}{description}{1}
\setlist[enumdescript,1]{%
  before={\setcounter{descriptcount}{0}%
          \renewcommand*\thedescriptcount{\arabic{descriptcount}}},
        font={\bfseries\stepcounter{descriptcount}Case \thedescriptcount,~}
}
\begin{document}
\begin{enumdescript}
   \item item one
   \item item two
   \item[Some Text] item three
   \item item four
   \item item five
\end{enumdescript}
\end{document}

---

The only difference, it that I would like to put the number after the custom text, and not before, i.e., instead of doing:

Case 1, item one
Case 2, item two
Case 3, Some Text item three
Case 4, item four
Case 5, item five

I would like to do:

\begin{enumdescript}
   \item[Some first] item one
   \item[Some second] item two
   \item[Some third] item three
   \item[Some forth] item four
   \item[Some Fifth] item five
\end{enumdescript}

Some first 1) item one
Some second 2) item two
Some third 3) item three
Some forth 4) item four
Some fitth 5) item five

Here is a solution: I create a new environment, which first redefines the \makedescriptionlabel command, then enters a description environment.

\documentclass{scrbook}

\usepackage{enumitem}
\usepackage{xparse}
\newcounter{descriptcount}

\NewDocumentEnvironment{enumdescript}{O{}}{%
    \setcounter{descriptcount}{0}%
    \renewcommand*\descriptionlabel[1]{%
      \stepcounter{descriptcount}%
      \normalfont\bfseries ##1~\arabic{descriptcount})%
    }%
    \description%
  }%
  {\enddescription}

\begin{document}

\begin{enumdescript}
   \item[Some first] item one
   \item[Some second] item two
   \item[Some third] item three
   \item[Some fourth] item four
   \item[Some Fifth] item five
\end{enumdescript}

\end{document}
