This is a 2009 Dell inspiron 537s. It has a Pentium CPU, which I could not find for the life of me, a motherboard that I have no clue about, no graphics card, and DDR2 memory. It is about the dustiest thing I have ever seen. When I opened it, I got a pain in the lungs and started coughing uncontrollably. It runs XP, and it can barely boot Firefox. The power supply has a bunch of Chinese lettering on it, so I am worried about the quality and weather my family will die in a fire when it eventually explodes. Bask in the glory of the 2009 537s.
