AD removal script?

Hi, I am trying to find a way to search for an AD object in powershell and delete it, So i have figure that out kind of. But what I really want to do is have the script check if the object exists first then delete it and if it doesn't find it give me a message that it is not found.

FYI the naming scheme we have for computer objects all start with DT.

I am a extreme newb, please be gentle with me.

I have actually been tasked with removing the object from many different locations including crashplan, SCCM, JAMF , Symantec. But I am starting to crawl before I can walk.

code is attached, am I even close to achieving what I need??

thanks,

John

$computerName = Read-Host -Prompt 'Input computer name'


GET-ADCOMPUTER  -IDENTITY $computerName 
if ($computerName -eq "Cannot find an object with identity")
{Write-Host "NO computer found"}


elseif ($ComputerName -eq "DT*********")
 {REMOVE-ADCOMPUTER $computerName -confirm:$True}
