Getting Remote PC Inventory from txt file build arrary

Seems I have lost the logic of this,  I think I need a foreach  statment

so far it will read the Pcs in the list and works great on one at a time but i need to read all PCs add the PC inventory into an array and out put it  later  and have option to output to Execl.

$PCs = Get-Content -Path "P:\scripts\PCs.txt"

$local = Get-Credential administrator

$bios = Get-WmiObject Win32_BIOS -ComputerName $PCs -Credential $local
$Proc = Get-WmiObject Win32_processor -ComputerName $PCs -Credential $local | Select-Object -First 1
$memory = Get-WmiObject Win32_physicalmemory -ComputerName $PCs -Credential $local
$system = Get-WmiObject Win32_ComputerSystem -ComputerName $PCs -Credential $local
$os = Get-WmiObject Win32_OperatingSystem -ComputerName $PCs -Credential $local
$Networks = Get-WmiObject Win32_NetworkAdapterConfiguration -ComputerName $PCs -Credential $local | ? {$_.IPEnabled}

$Object = New-Object PSObject
