I just received a call from a computer repair shop that I've been assisting at...
"Hey...I just opened this tower of the new computer that the customer left...there's nothing in it..."
What? The tower of a one day old, brand new Compaq CQ2010 contains almost...nothing. The day before, I went into the Base Exchange ("BX") on an Air Force base with an older couple to try to help them choose a new computer. From what they told me about how they use computers, I saw no reason to not suggest purchasing the least expensive computer that was available. Which was the Compaq for $299. And now, I know why the older woman had no problem lifting it...
Take a look at the specifications here.
And now...the motherboard:
Form factor: Mini-ITX form factor: 17 cm (6.7 inches) x 20 cm (7.9 inches)
Chipset: AMD Hudson-D1 FCH
Memory sockets: 2 x DDR3
Front side bus speeds: 4 lanes, 2.5 GT/s per lane UMI (Unified Media Interface)
Processor socket: Not applicable because the processor is soldered down to the motherboard
Notice anything missing?
(Answer: PCI slots.)
The technician who opened they case said the motherboard is about as large as those found in netbooks.
And, take a close look at the power input port: "DC input power". Just like they use for portable/notebook computers.
