This is my unassembled and reassembly of an old PC my grandparents gave me. It is about 17 years old and they got it because the government wanted every village to have Internet access and they volunteered.
The build went well and has given me some great experience of PC building. I'm only 13 and hope to build a PC in May so this has kept my building desire satisfied until then.
Currently it run Windows XP but that will soon change to Lubuntu if I can get it to work. The main problem I have is doesn't recognize my USB mouse. Luckily my Grandparents gave me an old keyboard (non-usb) so I can still access the BIOS.
The biggest surprise for me was how dust free it was although that may have been down to it not having any system fans.
