MIPS IV-subset
300 MHz (294.912 MHz)
128-bit integer SIMD
128-bit floating-point SIMD
24KB cache (16KB instruction + 8KB data)
16KB Scratch Pad RAM
Co-processor 1: FPU
Floating Point Multiply Accumulator (FMAC) x 1
Floating Point Divider (FDIV) x 1

450 Dhrystone 2.1 MIPS
6.2 GFLOPS

...

Main Memory

32 Megabytes RAMBUS DRAM
32 bits wide (dual channel 16-bit)
400 MHz (800 MHz effective)
800 megabits per second per pin
3.2 gigabytes per second bandwidth
Unfortunately only single precision...

The PS3 cell CPU will be much more interesting in this regard.

To get back to part of tom11784's question, one way to make use of that harddrive without loading the cpu (much) is to network other machines to it.

But the bottom line is, doing any data manipulation will take cpu time from some machine.

hey - i figured 1GB of memory, vs 60GB of hard drive space - perhaps some sort of manipulation could be considered

Silly me.

This countdown, which appears on http://www.mersenne.org/status.htm, is the countdown of how many exponents are remaining, not how many days.

Well if you go to Compression Agent and compress your drive, you can move all the free space to the hard drive and the stuff to G drive (which is made by compression agent) and it will increase performance. It even says it is a tradeoff between free space and performance.
