<#
.SYNOPSIS
This script displays key system information within a customizable styled layout.

.DESCRIPTION
The script fetches and displays information about the operating system, CPU, RAM, and other system details
in a visually structured format using box-style layouts. It provides options for various box styles and color schemes.

.PARAMETER Logo
The logo to display, which should be passed as a JSON object defining the logo text and its color properties.

.PARAMETER Info
The system information to display, formatted as a JSON object that includes text and its associated foreground and background colors.

.PARAMETER Box
The box style to use for displaying the information, defined as a PowerShell custom object with properties for each part of the box's border.

.EXAMPLE
New-Info -Logo $WaveLogoColored -Info $Info -Box $RoundedBox
This command displays the system information using a wave logo and rounded box styling.

.NOTES
You can modify the script to include more box styles, logos, or to fetch different system information as needed.
