2011 HP Compaq 4000 Pro SFF running Windows 7 Professional SP1 x64
I recently got this computer from my math teacher at the school I go to since she had this lying around, she offered to me if I could have it, and I happily accepted the offer, it also came with an Acer monitor from 2012 but I gave it to my sister since she needed a monitor for her PC and I already have a lot of monitors. I added a DVD drive since it didn't have one since it was originally from a homeschooling district and I upgraded the RAM to 4GB since it had 2GB of RAM.
PC Specs:
Intel Celeron E3400
Intel B43 Chipset
4GB RAM (formerly 2GB RAM)
250GB HDD
Windows 7 Professional SP1 x64
