QuakeMode

Try running this in your console:

$Host.PrivateData.Settings.ShowInTaskbar = $false
$Host.PrivateData.Settings.AutoHide = $true
$Host.PrivateData.Settings.AlwaysOnTop = $true
$Host.PrivateData.Settings.Animate = $true
$Host.PrivateData.Settings.Opacity = 0.8
$Host.PrivateData.Settings.BorderThickness = "0,0,0,5"
$Host.PrivateData.Settings.BorderColorBottomRight = "Red"
$Host.PrivateData.Settings.BorderColorTopLeft = "#CCFF3300"
$Host.PrivateData.Settings.WindowHeight = $Host.PrivateData.FullPrimaryScreenHeight/3
$Host.PrivateData.Settings.WindowWidth = $Host.PrivateData.FullPrimaryScreenWidth
$Host.PrivateData.Settings.WindowTop = 0
$Host.PrivateData.Settings.WindowLeft = 0
$Host.PrivateData.Settings.ConsoleDefaultBackground = "Black"
$Host.PrivateData.Settings.ConsoleDefaultForeground = "White"
$Host.PrivateData.Settings.FocusKey = "Win+OemTilde"
$Host.PrivateData.Settings.StartupBanner = $false

If you don't like it hiding on you automatically you can set $Host.PrivateData.Settings.AutoHide = $false , and if you're on a weird laptop keyboard you might want to set $Host.PrivateData.Settings.FocusKey = "Ctrl+Alt+P" or something else that's easier to type. If you find you're having a hard time remembering your FocusKey you should leave the window in the taskbar $Host.PrivateData.Settings.ShowInTaskbar = $true or disable the animation so it's always visible (for Alt+Tabbing to it) $Host.PrivateData.Settings.Animate = $false

Normal Mode

If you want to switch back to something like the normal window, you could try this:

$Host.PrivateData.Settings.ShowInTaskbar = $true
$Host.PrivateData.Settings.AutoHide = $false
$Host.PrivateData.Settings.AlwaysOnTop = $false
$Host.PrivateData.Settings.Animate = $true
$Host.PrivateData.Settings.Opacity = 1.0
$Host.PrivateData.Settings.BorderThickness = "2,10,2,2"
$Host.PrivateData.Settings.BorderColorBottomRight = "Red"
$Host.PrivateData.Settings.BorderColorTopLeft = "#CCFF3300"
$Host.PrivateData.Settings.WindowHeight = $Host.PrivateData.FullPrimaryScreenHeight/2
$Host.PrivateData.Settings.WindowWidth = $Host.PrivateData.FullPrimaryScreenWidth * (2/3)
$Host.PrivateData.Settings.WindowTop = $Host.PrivateData.FullPrimaryScreenHeight / 4
$Host.PrivateData.Settings.WindowLeft = $Host.PrivateData.FullPrimaryScreenWidth * (1/6)
$Host.PrivateData.Settings.ConsoleDefaultBackground = "DarkBlue"
$Host.PrivateData.Settings.ConsoleDefaultForeground = "White"
$Host.PrivateData.Settings.StartupBanner = $true

Incidentally, in case you're new to PowerShell, check out the PoshConsole Profile page to see how you can have all of that as simple functions so you can toggle between them by just calling Quake.
