I believe this is what you're looking for, and many will probably find something they want here.
Since the sunsite.unc.edu days downloading Slack with a 0.99 kernel, these guys have always given me great thruput even on crappy 2400 baud connections.
I currently work for a government agency. For a few weeks in a row I can go without having more than an hour's work a day, then bang, I go a week where I'd need to put in 20 hours a day to keep up. [...] But literally 3 weeks of sitting on my ass doing nothing? Do you have any idea how long these days are?
Yes. Followed by
I have to try and keep up with technology on my own time.
Sounds like you have (8*5*3) hours to work with whatever tech you want to. In my own case, I've used time like this to find new things to do / new ways to do them, impress management, and get promoted. Just a thought, but hell, if they're paying you to fiddle your thumbs then get your fingers in on the action and learn something.
I haven't had this experience. Dell cases are usually very easy to get into (well, the old ones were; the new ones are too, once you figure out how to get the first one open;-) and their support is top-notch. I've heard some stories to the contrary, but the number we received after complaining to one of their management types (this was before my time) was guarenteed to be answered within two minutes, and it always has.
They even tried their hardest to support Linux on an old 6200, way before any official word from Dell.
You are right, though, you have to convince their support staff that the [insert hardware here] is broken before they'll do anything about it, but once you do you'll either have a tech there the next business day, or the part in 2-3 days.
Overall, their product is decent, and their support is excellent. Not to say that we buy Dells anymore, I made sure we put an end to that (beige boxes all the way:).
I think the reason people get the impression that AMD chips are not top of the line, is because of the poor compatability with other components. I've had a lot of problems getting AMD chips to play nice with my other cards.
This was true with the K6-2's (or, rather, the chipsets that "supported" them). I "upgraded" to one, and was bitter for a long time, since it's AGP support was broken at best. However, I got an Athlon system at work, which convinced me to spend the money on a substantial system at home, and I haven't had a single problem or complaint with it - the Athlon kicks butt!
My digital watch could handle 100,000 hits per day. I tried ab (ApacheBenchmark, comes with Apache) on my workstation, which is significantly more powerful than my watch.;-) The config:
Athlon 850/512MB PC133/Adaptec 2940 (U2W LVD)/9GB Cheetahs. This was going through localhost since Apache, and not the network, is in question. Running RH62, default kernel, and more importantly, default Apache installation, with a slight system load (desktop crap).
Bottom line: 112 to 128 seconds to fulfill 100k requests. Page was the Piranha (static) login page. Taking 120 seconds as an average, that's 72,000,000 hits per day under constant load, on relatively cheap desktop hardware.
Using -k (keep alive) with 128 tasks, this even better: 71 seconds, 1396 hits/second, or 121.6 million hits per day.

WinDSL Coming?

I do not know about dsl, but a cable modem is actually a modem. The signal on the cable line is an analog signal, and has to be converted into digital information. Yes it is not converting an audio signal that you can hear, but it is modulating/demodulating so it is actually a modem.
DSL stands for Digital Subscriber Line. www.adsl.org.
There are only a few games I play, and TA is my all time favorite. I'd gladly pay twice what I paid for the Windows version for a Linux version. In fact, I have a copy of Win98 specifically for TA, which is kind of annoying to have to keep around.
I also have a K6-2/350, but it has a 100MHz bus, so there's no problem using PC100 RAM. As for overclocking RAM, I have done so (with that same system, actually). Depending on the RAM it can either be stable as a rock (and provide a significant performance boost), or utterly unstable.
I have seen boards with seperate jumpers for RAM and CPU bus speeds, but I'm curious to know if the RAM could be clocked higher than the CPU. I assume not, since the bus to the RAM is regulated by the CPU.
BTW, I have yet another board which uses DIP switches. And here I thought they had all been burned in the Great Purges.:)
The only problem with RAM is that newer Celerons have their multiplier locked (my 400A's are locked at 6). By default the bus is 66Mhz, which means that your RAM is also running at that speed, getting no gain from PC100 RAM. The only solution, unless your board lets you set the CPU and RAM clocks differently (it's possible to run RAM slower than the CPU, but I don't believe it can be done the other way around), is to overclock. I've been able to overclock my CPUs to a 92MHz bus, so there's not much loss. It all depends on the chip and board I suppose.
I also have the BP6. I'm using two 400A (Mendocino) CPUs. They're not overclocked at the moment because of cooling issues - they run at 55 degress C cracking RC5. However, I was able to overclock them to 572 running stable, if way too hot.
The ATA/66 support works great under Linux. You need to get the HPT366 patch (available from here or any other kernel.org mirror). The README says it won't boot from the ATA/66 bus, but it works fine for me.
The Win9x and NT support is fine, but get the newest drivers from here. After applying the newest BIOS flash I was unable to install Win2k, but with the earlier BIOS it worked fine.
Also, the BP6 website has some useful information.

The user interface is fine (due largely to the fact that they stole it from the mac)
More like they stole it from OS/2, right down to the single click close icons. But thru four iterations of Windows, they still can't give me transparency on icon text.:(
_A_ Linux swap file may have a limit of 128MB, but you can have _more than one_ swap file, which is probably on a completely different paradigm than that of the Microsoft developers.
Actually, that was a limitation in the 2.0 kernels. I have several 2.2.x (x=10/12) systems running with 256MB swap partitions.
What we need now is to have someone start LinuxFacts.com (or some other such name) and do things like benchmarking, stability testing, and basically serve as an "one stop open-source marketing shop".
And if I happen to crack that one special RC5 block then I've got a few grand to buy some new hardware. Besides, distributed.net's numbers are bigger.:)
Now then, I'm certainly not saying that these nations should not have help, by way of charity of other voluntary effort. It's not the dollars I'm opposed to, but the general principle. I simply do not believe that the proper way to make things happen is by taxing industrialized countries and passing the funds along to the less fortunate, from each according to ability and to each according to need.
I'd rather see the funds from any tax like this to go to major upgrades here in NA. Gigabit fibre to my living room, bring it on, and send our then outdated OC-3/etc technology to these nations. Kind of an infrastructure hand-me-down, the big kids get the new toys and the little ones get the rest. Seems fair to me, considering we're paying for it.
I haven't used it, but Intel sells their AC450NX "Server Platform", a quad Xeon board sporting five 64bit PCI slots and two 32bit buses for six 32bit slots. It also supports 8gig of ECC (isn't that architecturally impossible?)
