Pros: We bought several (8) of these when our Artists agreed to move to PCs. We planned to add more RAM, add an SSD, put in a better video card, and upgrade the power supply. These computers have a Core i7 processor, a decent amount of starting memory (single 8 GB stick), good-sized hard drive at 1 TB, and the tower isn't overly large. The case is pretty easy to get into and to work with. The included power supply is 80+ Bronze. Includes a basic video card. Overall quality seems fairly good.

Cons: Proprietary power supply connector (had to purchase adapters from a company in Hong Kong). The included power supply is only 280 Watts.

We put a GigaByte GV-N660OC-2GD GeForce GTX 660 video card into each of these. The motherboard is a little short for this video card, although we were able to fit the cards in by disconnecting the eSATA cable from the front. (We don't expect to need eSATA .)

Other Thoughts: We contacted Lenovo ThinkCentre support (provided by IBM in Atlanta) to request Win7 Pro media because we wanted to install the O/S on an SSD. They sent it quickly without asking for payment, which was unexpected. With just the SSD and no other modifications, the computer is nice and fast. Main hangup is the proprietary power supply connection since it meant an extra $20 per machine and a five-day wait to get the adapters in the mail.

Pros: Is now a speedy computer

Cons: Had to spend a lot to get it where I wanted it. Had to upgrade RAM, installed SSD, upgraded video card, and power supply.

Other Thoughts: I was debating on whether to buy a Dell XPS, this, or a Dell Precision. I decided to give the Lenovo a try. The XPS is about $200 cheaper and just as good as this machine. The video card it came with had very poor performance, so I tried to upgrade it, only to find that the power supply did not provide enough juice, so I had to upgrade that too, and also had to order an adapter from China, because Lenovo uses a 14 pin power connector, instead of a 24 pin like everyone else.
