I purchased this same Lenovo ThinkCentre M72ecomputer from this same seller in April of 2021 to replace an old refurbished Dell I had for a long time. It lasted 2 years, I paid $129 with tax then.This one to replace it was just $97 and it works great. No dvd player installed, BUT, a USB DVD player, Mouse and Keyboard were included all for $97...!I like these old desk tops because they have all the familiar plugs in the back, I can switch them out easily.My first one was running very slow and having pre-crash notices, then it just died. But I ran it all weekend long and all night during the week listening to YouTube sleep wave sounds with external stereo speakers, so it put in a lot of hours in 2 years.This new one that I got to replace it started up perfectly, loaded my Norton Anti-virus and Super Anti-SpyWare and my Chrome browser, some photo editing and an extra browser,  it was like a new High Performance Machine. I guess I got a good one not made on a Monday or Friday.  :)HERE'S A TIP to extend the life of these old worn refurbished computers. HEAT IS THE MAIN THREAT, I like to remove the side cover and use a Quiet Stainless Steel Fan to keep the Hard Drive and Processor cool. It really helps. About every 4 or 5 months I'll take the open sided computer outside and gently blow out the dust with the leaf blower.This also helps to extend the life, at least 2 years of hard running, for less than $100. GREAT DEAL... !(check out the pics)
