The computers arrived quickly and were configured as described in the listing.  While reloading they seemed exceptionally slow compared to other systems.  After some testing, it was discovered that the "Adapter Warning" option was disabled in the BIOS.  When enabled the computer provides a warning that the system will be throttling down due to a potentially incompatible adapter.The adapters sent with the computers are variable voltage and current and therefore the computers throttle down to 792MHz (vs. 2.8GHz) due to the variable voltage input.  Do yourself a favor and spend the extra $35 dollars for the 65W Dell OEM adapter (Part #: MGJN9).
