It's a solid little unit that sits flat on a desk, and a monitor can be placed on top of it. It features a lot of modern connections, including Gigabit Ethernet (Intel model 82567LM-3), eSATA and DisplayPort, but it lacks a more common DVI port. This isn't an issue, though, as you can either choose a DVI bracket or a DisplayPort-to-DVI adapter during the ordering process.
There are six USB 2.0 ports on the rear and two more at the front, while on the inside there are two low-profile expansion slots: one PCI, and one PCI Express x16. This gives the Lenovo ThinkCentre M58p good scope for expansion should there ever be a need to install a more powerful graphics card or a wireless networking adapter, for example.
The configuration of the Lenovo ThinkCentre M58p PC is solid, and it produced good results in our tests. Our review model came with an Intel Core 2 Duo E8500 CPU running at 3.17GHz, integrated Intel GMA 4500 graphics, 2GB of DDR3 RAM, and a 7200rpm, 250GB SATA hard drive (Seagate's ST3250310AS). In WorldBench 6 this configuration mustered a score of 106, which is a good result. The PC's power was also reflected in the Blender 3D and iTunes MP3 tests, in which it recorded times of 57sec and 53sec, respectively. Basically, it's a PC that will handle almost any office task you throw at it, and because it's a dual-core CPU, it will multitask efficiently.
