Comments about Lenovo ThinkCentre M91p Tower Desktop Computer (Black):
I'm a big fan of Lenovo. I'm not, however, super keen on the way that this product was described on the B&H site. The listed video card was not installed. So, I had to purchase a card separately to run dual monitors. Which brings my to my second point. Not a lot of scalability on the motherboard. There is only one PCIe slot. I installed a PCIeII graphics card, and the weird placement of the SATA outlets on the mother board caused one of the 4 to be rendered useless, since it was blocked by the card. Which brings me to my third point, the power supply only has enough cable to run what comes in the box. So, I had to replace the power supply to run the graphics card, and additional HDD that I installed. If I had to do it over, I would have just built the box from scratch.
Having said all of that, the machine runs perfectly, now that I have worked out all of the hardware kinks, and I am still a huge fan of Lenovo.
