So here is my server XD kinda unattractive and cramped but it gets the job done. It consists of 2 Dell OptiPlex 7010 USFF computers. Each PC is about $500 but I got them for free. If you want me to tell you about that ask in this thread.
SPECS (Both PCs are the same.):
Intel 3rd generation Core i7 Quad Core @ 3.10 GHz
Windows Server 2012
4 GB DDR3
1 TB HDD
The main server acts as a mail server, web server, print server, email server, and a file server. The secondary server is for hosting game servers. They are both in a closet in my family's computer room. They used to be in my room but it got so hot so I moved them.
I will possibly do a video tomorrow.
