Enter the HP Pavilion dv8125nr. It's a 17 inch notebook computer from the post desktop processor notebook computers era. It has a single core
1.8 GHz AMD Turion 64 Mobile ML-32 processor at 35 watts. Standard configuration is 512 MB (2x 256MB) memory with 2x 80GB HDDs. The fact that this particular computer can support 2 PATA HDDs is particularly exciting! I got this particular notebook computer from a coworker and I'm performing the standard upgrades (processor, memory, and SSD).
Another interesting aspect of this notebook is that it supports both the 32 bit PCMCIA slot (on the left) and the 64 bit ExpressCard slot (on the right). In theory, this is a 64 bit computer because the 1.8 GHz AMD Turion 64 Mobile ML-32 is a 64 bit processor. However, due to the 32 bit PCMCIA slot, it's best to leave the the operating system at 32 bits otherwise, the drivers won't work.
