After over a year of perpetual issues with this machine I finally snapped.
After a through erase the drives will go on eBay, as will the case. The accursed ATA controller cards will go down the garbage chute and at the moment I'm giving 50/50 odds on the motherboard, CPU and RAM, following them.
The central processing unit (CPU) is the portion of a computer system that carries out the instructions of a computer program, to perform the basic arithmetical, logical, and input/output operations of the system. The CPU plays a role somewhat analogous to the brain in the computer. The term has been in use in the computer industry at least since the early 1960s.The form, design and implementation of CPUs have changed dramatically since the earliest examples, but their fundamental operation remains much the same.
On large machines, CPUs require one or more printed circuit boards. On personal computers and small workstations, the CPU is housed in a single silicon chip called a microprocessor. Since the 1970s the microprocessor class of CPUs has almost completely overtaken all other CPU implementations. Modern CPUs are large scale integrated circuits in packages typically less than four centimeters square, with hundreds of connecting pins.
Two typical components of a CPU are the arithmetic logic unit (ALU), which performs arithmetic and logical operations, and the control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
Not all computational systems rely on a central processing unit. An array processor or vector processor has multiple parallel computing elements, with no one unit considered the "center". In the distributed computing model, problems are solved by a distributed interconnected set of processors.

Got a quick close up of my motherboard before I started assembling and installing. Lots and lots of details in these things. Crazy.

There is only one Stanley Cup but I guess you could make your own. Someone at Microsoft was very clever
Great for the office or a Geeky desktop accessory! This computer bug is well contained within a "habitat" 60mm x 15mm plastic petri dish with a keyboard circuitry base. Each bug is completely unique!

Yeerk
A Yeerk is a parasite that takes over the body of another being by infesting a host's brain through their ear canal. Yeerks in their natural state have decent senses of smell and touch, but they are blind until they enter a host, as they do not have eyes. They possess antennae-like protrusions called palps, as well as osmosis nodes, small organs that process nutrients in the Yeerks' native pools. Although the presence of a circulatory system of some kind is debatable, apparently Yeerks have no hearts, as evidenced by the description of a human morphing into a Yeerk, in which the human heart stops and dissolves away completely.
Yeerks communicate in their natural state using a language of ultrasonic squeaks, and use sonar to get a basic picture of the surroundings.
