PowerShell add objects to body of email - powershell

Question

I want to be able to collect information from this script and put it in the body of an email. For the most part it seems to work except I want serialnumber, osversion, model, loggedin on different lines in the body of the email.
[CmdletBinding()]
param (
$computername = (Read-Host "Enter Computer Name"),
$subject = 'Serial Numbers',
$to = 'test#test.com',
$bcc = 'test#test.com',
$body = $Collection,
#$body = (Get-Content -path "c:\powershell\serialnumber\SerialNumber.csv"),
#$mail = "mailto:$to&subject=$subject&body=$body",
[string]$ErrorLog = 'c:\powershell\useful\errorlog\retry.txt',
[switch]$LogErrors
)
[Array]$Collection = foreach($computer in $computername)
{
$os = Get-WmiObject `
Win32_OperatingSystem -computer $computer
$bios = Get-WmiObject `
Win32_BIOS -computer $computer
$model = Get-WmiObject `
Win32_ComputerSystem -computer $computer
$Monitor = Get-WmiObject -computer $computer WmiMonitorID -Namespace root\wmi |
ForEach-Object {($_.UserFriendlyName -notmatch 0 |
foreach {[char]$_}) -join ""; ($_.SerialNumberID -notmatch 0 |
foreach {[char]$_}) -join ""}
$body = New-Object -TypeName PSObject -Property #{
Computername = $computer;
LoggedIn = $Model.username;
OSVersion = $os.Caption;
SerialNumber = $bios.SerialNumber;
Model = $Model.Model;
Monitor = $Monitor;
}
#$obj | convertTo-csv | out-string
#$obj = $body
#$Collection = [string]$body
#[String]$Collection
[string]$body
Start-Process -FilePath "mailto:$to&bcc=$bcc&subject=$subject&body=$body"
}
$Collection

You can't use an object directly as the body of an email, it must be a [string]. Try this:
$body = New-Object -TypeName PSObject -Property #{
Computername = $computer;
LoggedIn = $Model.username;
OSVersion = $os.Caption;
SerialNumber = $bios.SerialNumber;
Model = $Model.Model;
Monitor = $Monitor;
} | format-list | out-string
