The Intel D53427RKE inside the Logic Supply ML300 system.

The Intel D53427RKE board defines almost every aspect of the system's performance and capabilities. Its Core i5-3427U is a high efficiency 17W TDP dual-core with 3MB cache and hyperthreading, clocked at 1.8 GHz with 2.8 GHz Turbo frequency. Built in Intel HD Graphics 4000 runs at 350 MHz, with max dynamic frequency of 1.15 GHz. The board is normally equipped with a low profile blower heatsink for the CPU, not used in the LGX ML300 system.

Accessories with the sample system included:

  • Windows 7 disc
  • bracket kit for mounting the system to VESA-standard, horizontal/vertical surfaces, or DIN rail clips, four stick-on rubber feet,
  • Delta Electronics external 19VDC 65W AC/DC adapter with AC cable. The Delta runs on 100~240VAC, outputs 19VDC, and is rated for Level 5 (highest) efficiency as per the International Efficiency Marking Protocol (rev. Oct. 2008, PDF), referenced by Energy Star. This rating describes efficiency to be at least 87%.

Cover/heatsink half of the ML300 chassis. Note the two raised square portions to which the CPU and PCH of the board clamps when it is installed.

In the ML300 case, no heatpipes are used for heat transfer. Instead, on the underside of the cover, there are two raised blocks of aluminum, one for the CPU and one for the PCH. When the board is mounted, those chips make tight firm contact with the aluminum blocks, covered with TIM, of course. Conduction to the ribbed casing top enables most of the heat disspation, but the entire aluminum casing helps with cooling.
