I know from a server, which came into operation beginning this year and working also for E@H, constisting of 665 dualcore processors of AMD Opteron. They did choose this processor, as they got maximal FLOPS per money.
If you do crunch for E@H not only at idletime during normal working with the computer, but let him run all time, then it´s worthwhile to take into consideration the crunchingspeed per electrical power - FLOPS/Watt -. At increasing energy cost this becomes of more importance at long operational times.

Good point!

My little Mac MINI with Core (1) Duo can generate about 700...800 credits per day at 40 Watts ! Try to beat that :-)

My c1D 1.73 laptop has a RAC

My c1D 1.73 laptop has a RAC or 640 for around 35-8W. Credits/watt is generally going to be highest with laptop grade hardware since every component is designed to be low power. The mac mini and any PCs in the same form factor (not sure if any major brands sell them, or if they're strictly DIY) are built primarily if not exclusively out of notebook parts.

FWIW, the claim was that a system through Alienware would be "much(!) more expensive!". This is what I just priced through Alienware. The 5355 is "slower" than the 5365, but you'll note that this system includes a FAR superior video card, a better sound card, acoustic dampening, a 10000 rpm OS drive (probably a raptorX), twin 500GB HDDs with data mirroring (RAID 1), and a high-end 5.1 speaker system, all for $200 less than the MacPro.

Also, let's say that I want to upgrade the video card again a year from now. That will likely be a lot easier to do on the PC side of things than the Mac.

Macs are good machines, except they're overpriced, especially given their lack of upgrade options...

I forgot something: the matching 8GB memory configuration (4x2 vs. 8x1) for the MacPro pushes the cost of the Mac up another $400. Reconfiguring the Alienware system to not have RAID 1 pushes it up by $140.

New prices:
Alienware - $7909
MacPro - $8300

In any event, "much(!) more expensive!" is not true...and in fact, one could argue that the Mac is actually "much(!) more expensive" due to the feature differences, particularly the slower video card and the lack of a powerful 5.1 speaker setup along with it.

If all I wanted to do was

If all I wanted to do was crunch BOINC, I would not need most of the stuff you list. A Dell 490 with *TWO* (count them: *TWO*) of the Xeon Quad Core CPU chips [Quad Core Intel® Xeon® Processor X5355 2.66GHz,2X4M L2,1333(ESMT)] and a mere 2 GB of RAM and a simple 80 GB hard disk can be had for just over $4,100 without a monitor. Bump it to 4 GB of RAM, a bigger hard disk, and a reasonably low-cost monitor and you could still get it under $5,000. Amout half of that price is the cost of the two CPU chips (over $1,300 each from Dell today).

An equivalently-configured Mac Pro runs about the same cost ($4,300 with 2 GB of RAM, but has a bigger hard disk as the default).

Of course, you can choose to add whatever bells and whistles you care to add to either machine. But by and large, you get what you pay for.

For whatever its worth, I have a 5-year-old Dell Precision myself (dual Xeon CPU chips). I tend to NOT buy the top speed versions. I get more bang for my buck buying the low speed versions of the top architecture.

If I did that with the aforementioned Dell 490, I could get *TWO* of the Quad Core Intel® Xeon® Processor E5320 1.86GHz,2X4M L2,1066(ESMT) CPU chips and the price out the door would be under $2,600 (for the $4,100 system above). If I had $5,000 (or more) to spend on BOINC contributions, I could buy multiple copies of that $2,600 machine (with a KVM switch, of course) and I bet that my total BOINC contribution (credits) would be a lot better than the person buying the Mac Pro with dual 3 GHz CPU chips.

And now, you know why I buy at the low end of the top architecture: it boils down to money, and ultimately, to "bang for the buck."

As always when discussing computer stuff, YMMV!

But not "per day". The mac Mini consumes (under full load) ca. 40 Watt (the electrical power, equivalent to the horsepower of a car). This amounts to 24 h * 0.040 kW = 0.96 kWh per day (this is the energy consumed). At german end-consumer prices, this is less ca 17 cent per day or only ca. 5 Euros per month!

Is that the system draw or the CPU power consumption (with or without the LCD turned on)? If that is the total power drawn by a mac mini that is very impressive, my CPU alone draws 105 Watts of power, and overclocked is probably well over 130 Watts. For four cores that is pretty good, but you throw in a water pump and three fans to help cool it and I'm looking at somewhere near 150 Watts for the CPU alone.

Just the whole Mac Mini, tiny white-aluminium box with a Core Duo, without display. The Apple integrated in an LCD was the iMac, with faster Core 2 Duo CPU.
