Actually, that's the opposite of what happens. A peltier element sucks heat off of one side of the plate and spits it out the other. This means that while your CPU has had the heat removed, the heat is still ejected out the other side, into the case. Running a peltier element actually INCREASES ambient case temp!!
I would not recommend peltier cooling to anyone except for overclockers (which I am, having run a dual celeron 400 @ 550 for months at a stretch) or supercautious Athlon fans. Peltiers require MORE case ventilation, not less.
Personally, I'd like a nice fast transmeta 1-4u box with integrated shitty AGP graphics and striped quiet 7200RPM ATA66 drives for less than $1.5k. I would power down my 4u homebuilt in a heartbeat.
The results look nothing like the compiling benchmark, and have convinced me to start a web hosting company using OSX Server on Macintosh hardware.
Maybe I'm a hopeless aesthete, but I wouldn't do that yet until Apple releases proper rackmount servers with redundant hotswap fans/PSUs/HDDs. They know how to do it (They even used AIX), it just hasn't happened with a G4 yet.
Also, I'd hope that they'd release a server with an improved memory interface (multichannel PC2100) because web servers love memory bandwidth..

Irony alert: my Jeep was built in Canada, thus providing jobs and income tax for the Ontario economy. Though it is technically still considered a "domestic" American car by the US FedGov..
It's a *fair* system... but because the government is involved, there's been call to dismantle it.
Part of that whole 'Friendlier for business' push I've been hearing about? I certainly hope your civic leaders are keeping a close eye on what happened with privatizing the Calfornian electrical utilities (I'm sure they are, they're certainly making lots of Accounts Receivable selling power to them, which as a New Yorker I say squeeze those envirohippies until they bleed;) and what the consequences are of doing something the wrong way.
I mean, the Prius looks like an Echo, which is possibly the ugliest car in the history of US motoring.
BZZT! Wrong! Thank you for playing.
The ugliest car on North American roads now is the Pontiac Aztek. It's old-skool 70's butt ugly. It isn't even cuddly-ugly like an A-10 warthog. It just needs to be taken out and shot, along with its designers.
If you *really* want to see automobile pollution and gas consumption dramatically reduced, call for an end to the SUV trend.
Why? It's the only kind of vehicle American companies can manufacture that competes favorably globally as well as generates large profit margins reliably. Let's see if they can transition into a more responsible form: this will only happen if consumers demand it. Government intervention can only ever be a bad thing, for individual liberty AND the economy, AND the environment. At least, it would be obvious if you read up on the more stupid things FedGov has done.
Thanks to well-meaning CAFE requirements and bloody insurance companies, I as a 28-year-old can't affordably own a V8-powered Camaro because of insurance issues, but I can (relatively) easily insure a V8-powered Jeep Grand Cherokee. The Camaro is faster, more efficient, more maneuverable, smaller, lighter, etc. But too many teenage punks get into wrecks in them, and that causes my insurance to cost.
Also, thanks to CAFE, fast cars with big engines are expensive to make and certify, and require larger numbers of fleet econoboxes to be sold (at a razor-thin margin or even loss thanks to competition) in order to compensate for their lower economy. Light trucks (SUVs) are not subject to the same CAFE regulations, so you can easily have your high-output V8s in them instead, and do so relatively cheaply.
Several years of gas costing more than $2/gallon will effectively kill the SUV trend without loathsome political meddling. It will also cause older, more polluting, less efficient cars (which are owned by under/noninsured low-income folks, or fixed-income oldies who shouldn't be on the roads to begin with IMAO) to come off the road, thus cleaning up the air and reducing traffic. BTW, modern SUVs have lower emissions than pre-1990s cars of equal engine displacement.
Personally, I believe that we should:
elect a government we can trust, that will staff with reliable managers
provide for a regularized national auto insurance plan, where private industry can bid for a number of autos randomly distributed across the country and across age/sex groups (that is, "I'll take 50,000 people at $1600/yr" style bids)
charge a federal gas tax that will cover that insurance
administer it with no more than 5% administrative costs
If that works, then add a charge to buy all toll roads and include federal road funding (via disbursement to states based on use statistics) in that tax as well.
Do I think we'll even achieve step 1 within the next decade? I doubt it. However, you get lots of neat fringe benefits from that, including getting old people off the road, promoting mass transit (and watch out for the storm in the mass transit civil service world when additional millions of Americans wake up to the mass shithole that passes for mass transit in most of our cities), cleaning the air, and reducing dependance on imported oil.
I like plans that kill several birds with one stone, it's just important to keep an eye out for collateral damage.
(2) Disksuite is a free Volume Manager that does various levels of RAID.
However, it requires a lot more legwork.
You pretty much have to slice and dice your HDDs identically (and have identical HDDs in the normal case). Thus, you are still limited to 7 partitions (minus some for metadbs of course) within a "volume".
Also, you only get concatenation when you want to increase filesystem sizes, and fairly dumb concatenation at that. And IIRC if you want to concat you have to take the filesystem offline.
Disksuite is nice for small systems and root/boot/swap mirrors. Much nicer IMHO than setting up similar service (converting a single disk R/B/S system into a mirrored one) in Linux using md. I just did both on separate boxes in the last week, and I am still cringing from the md mirror "procedure" (though it did remind me that I actually don't suck;)
A true LVM beats DS up and down the square. Many flavors of Unix come standard with LVM for "free" (though you usually have to license the OS, and Sun now beers it away up to 8 CPUs) and IMHO it's about time for Sun to give it away as well, whether they license Veritas or port/write another solution.
ps: when you've got your kernel installed into the boot sector and you've gotten your / to start mirroring (by in my case booting from rescue cdrom, copying over the/dev/md instances into the ramdisk/dev, insmodding md, raid1 and reiser, mounting the partitions to mirror, chrooting to that mntpoint, editing lilo.conf (btw that's the LATEST lilo with md bootsector support) and/sbin/lilo), BE SURE to specify your md=X,/dev/hdeX,/dev/hdgX for your root drive in your kernel append for your mdX mirror label.
It's days like that you don't feel overpaid.;)

May ask for a moment of silence for the CPU? First IDE, now CPU heavy filesystems?
I have recently built a firewall server with 2 ATA33 drives mirroring each other via md raid1 (all reiser except/boot) at boot. Getting it to work (chicken + eggery abounding:p) was a challenge, but be that as it may, I'm so far pretty happy with it. I have used linuxrouter in the past and I gotta admit, I like having all my utils on the fw box. It only runs opensshv2, syslog client and kernel stuff, so hopefully it will be relatively hard to r00t.
This firewall box has 256MB PC133 RAM and a Duron 750. This is probably about 4x more RAM and 6x more CPU than necessary.
For server situations, CPU is so cheap that I believe you should pile on as many options as possible, as long as they're optional. modular plugin filesystem functionality is really really cool, and if I can plugin a steganographic encryption system (or choose to build it in statically as long as its presence is 'masked' somehow;) that would IMHO be very very rock.
... if you use Mandrake, buy it. Especially if you're an overpaid sysadmin that uses it to make impossible things look effortless. That goes for any distro, any flavor.
I just paid for my 8.0 powerpack preorder, and when I built an OpenBSD firewall I bought my copy of 2.7 (and paid more for the shipping from.ca than the actual discs!!). I could afford it, so I did. Good karma all around.

Everything they sell has a SKU and a barcode. It is all in the computer. Decent software should be able to handle this relatively easily, and decent hardware should push it thru very quickly.
They're offering the challenge to web app systems (DB + J2EE).. You'd need to find a really fast J2EE solution for Linux (is WebLogic ported?), and even then the contest T's and C's are kinda harsh (we get to tune your production system for 90 days is one...)

Also, keep in mind that SS2k runs out of gas at 300GB bases, due to scalability issues with its underlying OS. Linux 2.4 currently has similar limitations (shown by the SGI system getting only about 40% more performance with 2x the CPUs:p).
