Summary: Overall I am happy with this refurbished computer. At first I was skeptical but this ended up being a good deal. Video card has a good amount of dedicated memory so seeing youtube videos in 1080p is very smooth. Would definitely recommend.
Pros: works fine, is ddr3 and has 4 ram slots so ram can be easily and cheaply upgraded now or in the future, 3 open slots. Tou can put in a pci, or pci-e low profile wireless card. Fast enough for the average joe net use and word, would not recommend for much else though.
Cons: Mine came with a big dent on one corner, still works fine though, other than that nothing to really complain about. took off 1 egg for the dent.
Small size. Good performance. Quiet. Good Mfr. support.

Summary: Be aware that this is a mini-ATX machine. Called Small form factor by Lenovo. Only has 2 expansion slots. (1) PCI 16x for a graphics card. (1) regular PCI. No PCIe slot. The real model number machine I received was a M58P/6137 A1U. PS is 280 watts so this is not a gaming machine but the CPU is a 3GHZ core 2 duo. Video is good. 1900x1200 works OK. Has a displayport for a second monitor or driving an HD TV, which is what I am going to do.
