I got this Huge PC for $4.50

Hi Y'all! I went to the Thrift Store today (because I love to do so) and spotted this huge PC all the way down the shelf in a corner. I did not notice it at first but then later on decided to check. The PC had a huge sticker on it saying "Does not work HDD removed", nothing else and 2 price tags with $4.50 on it. It seemed in great condition except something missing on the front, so I decided to try anyway. I came home, plugged it in and guess what; The PC turned on fine and there WAS a HDD installed with Windows XP on it. It was not even formatted, but I did remove their files though bc privacy.

What should I do with this PC? Anyone have any tips? Thank you! 😇

This is a HP Proliant ML310. It has a Intel Pentium 4 2.2 GHZ. 1 GB Ram 2 Disc Drives USB 2.0 and Ethernet ports, parallel and serial ports.
