You are an IT consultant.
Your client just got a large account and needs to upgrade their network from the ground up.
With this large account, they need to upgrade to a Fast Ethernet network.
They need 10 client computers total for day to day business needs (nothing fancy), as well as a file and backup server, printer, and networking hardware.
Price out everything for this. You will need to list what client computers you will suggest including the details of these machines, along with what networking hardware you decided they should use, and most importantly why you are suggesting it.
Make sure you give the cost per piece of hardware and include everything down to the networking cables. The client will plan on using Windows 7 for their clients as well as Windows Server 2012 for their server(s).
