Simply get computer name with serial number

Hi All,

I use the script below to get serial number, but I have no idea how to get the computer name in the meantime.

Pls point me.

$File = [System.IO.File]::OpenText("d:\111.txt")
 while($Machine = $GuyFile.ReadLine())
{Get-WmiObject -computername $Machine win32_SystemEnclosure }
$GuyFile.Close()
