The ThinkCentre M90p is a high performance corporate PC from Lenovo that conforms to what they call their ultra small form factor. In essence it is an updated version of the M58p, moving from Core 2 and DDR2 to Core i5 and DDR3. Like the M58p, a main marketing point for M90p is its eco-friendliness; it has several environmental certifications including EPEAT Gold, Energy Star 5.0, and GreenGuard. While a green machine is a nice bonus for an individual, for corporations that often deploy fleets of identical PCs that may operate 24-7, this is no small matter. Energy efficiency in particular is absolutely essential.

Lenovo ThinkCentre M90p sample bundle.

The M90p conforms to the same physical dimensions as the M58p with its innards compacted into a 238 x 275 x 79 mm form. Of course with the tight confines comes limited expansion — the case has but one hard drive bay and only a single open PCI low-profile slot. The system is powered by a dual core Intel Core i5 processor, so it should be more energy efficient than its Core 2 driven predecessor, and thus potentially quieter. Despite being as powerful as many desktop PCs, it ships with only a 130W 87% efficient AC-DC power brick rather than a typical internal power supply unit.

19.5V/6.66A 130W AC/DC adapter.

The sample configuration we received has a few upgrades over the base model including a faster processor, more RAM, a higher capacity hard drive, an optical drive, and Windows 7 Professional rather than Home Premium. These improvements tack on an extra $200 to the price according to Lenovo's website.

On paper both configurations of the M90p seem heavily overpriced given the hardware, but it isn't actually possible to build a comparable system as there are no mini-ITX motherboards using the Q57 chipset available in retail. Q57 has several management and security features that may come in handy in corporate environments. For reference the slim OptiPlex 980 from Dell with more-or-less equivalent specifications to our M90p sample configuration can be ordered for about $80 less, though Dell's enclosure is a bit taller, 2 inches wider/deeper, and uses an internal power supply.
