    I wouldn't think you'd go to the trouble of building a really efficient computer without doing likewise with the monitor.

    Well, for starters, obviously go with an LCD. Then, the real problem becomes figuring out the difference between the wattage rating and the "real" draw.

    Currently, for my primary, I have a BenQ FP222, which they spec at 49W (not too bad, most 22" panels rate at 55W). It actually draws around half of that (which seems mostly influenced by how bright you want it), in my experience. I would love to see a real-world comparison of a large number of 19-22" LCD panels, because they all seem to publish draws far, far above what they really use; but no such list exists, that I know of.

    But when you say "go to the trouble", I can't help but think I haven't stressed enough how easily anyone can build a decent low-power rig, without skimping on performance for anything except hardcore FPS gaming. I really didn't do anything special, except picking a good CPU and not getting carried away with picking a GPU massively overpowered for what I want (for reference, the NVidia 7300 series sips power, and a bit higher end, the 8600 looks good if I had to build a new machine today).

    Also, the motherboard you pick can have a HUGE influence on power consumption. For example, picking a board with the ATi (now AMD) 790x chipset over any newer NForce chipset (680i, 780i, or really anything since the NForce 4) will save you a whopping 40 watts alone. Yeah, 48W total - Your chipset can now eat more than the CPU itself!

    Laptops feel "weaker" than comparably-spec'd desktops for quite a few reasons...

    Can you share details?

    Sure. Start with a VIA Epia LN10000EG (I personally use LogicSupply for my mini-ITX shopping, they haven't screwed me yet). Toss in a gig of DDR2 533 RAM. Get the lowest wattage SeaSonic PSU you can find (or other known quality unit - You will regret saving $30 here).

    Get any ol' $20 ATX case with four (or more) external 5.25 bays. You obviously don't need one with a PSU, but you'll find that it costs less to get one with power and toss the stock unit.

    Get a ThermalTake A2309 iCage (NewEgg carries these), the best $17 you'll ever spend on computer parts. I put one of these (or something comparable) into every machine I build, and it holds up to three HDDs (perfect with a fourth bay holding your optical drive).

    You may want to get a gigabit NIC card rather than using the onboard 10/100. You could also get the... Hmmm... I think Epia EK12000EG, a similar board that has an onboard gigabit NIC, but it costs almost twice the price for basically just that one feature. You also will probably want to get a loose 12cm fan to blow in the general direction of the CPU - Officially the LN10000EG works fanless, but in practice it can get pretty warm.

    And there you go... Everything you need except the actual drives, for under $250. Toss in a DVD burner and a 500GB drive (currently the "sweet" price point) or three, install your favorite Linux distro, and you have an instant home file/media server drawing only 30-50W (depending mostly on what and how many HDDs you put in it; you can also force-throttle the CPU in the BIOS to squeeze out a few more watts) at the wall.



    One warning about drives, though... I've had horrible luck with VIA's SATA drivers for Linux. I'd recommend sticking with the PATA for now, or even going so far as to run Windows if you must use the SATA port(s). And for the record, I do not recommend the marginally-cheaper Epia clones such as JetWay. I've only dealt with a few of them, but they without exception have sucked, and hard.

    No way your computer draws only 65W, unless you have a VERY old computer or a shuttle that can barely do anything.

    Provide an email address and I'll send you a picture of a Kill-A-Watt reading in the high-50W range with the CPU pegged (and in the low 40s idle). I respect your pessimism, but really do run two such systems; One even has something vaguely resembling a decent GPU, though no doubt the hardcore gamers would sneer heartily at it (not that I care, as I said, as I mostly prefer RPG and RTS over FPS).

    As for "older", AMD has two entire lines of modern, dual-core chips running between 31W (Turion) and 45W ("BE" parts). While true that dual 2.3Ghz cores don't rock the world anymore, as I said, they perform so much more than "okay" that I don't see myself upgrading for at least another two years (barring any revolutionary advances in CPU technology before then, which looks exceedingly unlikely IMO).



    Not to mention your power supply is at max 85% efficient.

    I've had enough crappy low-end PSUs take out systems in the past that I buy only the best now - And as a side effect of "quality", you tend to get "efficiency". I personally favor SeaSonic's hardware, of which the newer ones push 88% efficient; Though yes, the ones I have now only claim 85%.

    Regardless, keep in mind that that number applies multiplicatively to whatever your CPU and GPU (and the negligible rest) draw... 0.85*(35+16) wastes only 9W, while 0.85*(120+107) wastes over 40W. Just think about that for a sec - A carelessly designed midrange PC can easily waste, just in PSU losses, my total light-use draw.



    or a shuttle that can barely do anything.

    I run one of those (well, a home-built EPIA system) as my home file server. 22W at-the-wall (not counting the bank of HDDs except the boot drive), and it can perform its one and only real "task" (saturating a gigabit network connection) juuuuuust fine.

    It's sad that the industry is still sticking to the x86 instruction set.

    Why? Once upon a time, the x86 ISA had too few registers. Today, that problem has vanished (simply by throwing more GP registers at the problem) - And even then, so few people actually see the problem (and I say that as one of the increasingly rare guys who still codes in ASM on occasion) as to make it a non-issue, more a matter of trivia than actual import.



    The Power/PowerPC architecture was good

    I know I risk a holy-war here, but: No, not really. PPC didn't suck, and held its own for its era. But it didn't scale well, it always cost significantly more for a given level of performance, and even its biggest advantage, "Vector" processing (aka SIMD), vanished with the introduction of the original MMX into the x86 line. After that point, only clock speed and number of execution units mattered (and of course price, never forget price), and the PPC simply fell further and further behind. Apple "switched" for a damned good reason, and "Intel Inside" doesn't describe it.



    It should've been replaced a long time ago with a pure RISC instruction set especially now with the quest for less power-hungry chips

    First of all, all modern chips have a native RISC-like core with an x86 frontend implemented entirely in microcode - So if the world still wanted PPC, Intel could release a C2D tomorrow that exported that as the visible interface. Arguing CISC vs RISC in today's world has as much meaning as arguing over case colors.

    Second, the CPU's ISA has no (direct) effect on power consumption. RISC processors traditionally drew less power because they simply had fewer transistors (and a painfully small instruction set to show for it). A "modern" RISC processor, with multiple cores, multiple deep pipelined execution units, a variety of FP and SIMD units, and multiple levels of fairly large cache, would draw power comparably to anything currently available from AMD or Intel.
