What’s the objective of this project and exactly what ‘extra stuff’ are you talking about? Is the alternative power supply a diesel generator or something? ---

OP: are you really familiar with what makes a mini-ITX distinctive, or is it just something someone is suggesting to you? Because you might be better off with [MicroATX](http://www.pcgamer.com/head-2-head-mini-itx-vs-microatx-systems2015/), and I suspect that all you need is a “small form factor” PC, like some of [these](https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=sff+pc). (Most mini-ITX and MicroATX links I’m getting are build-your own systems, and frankly, asking " Is it possible to use power from the rolling wheels or a gyroscope to provide power for the cooling fans?" means that you probably aren’t in the “roll your own” market niche.) ---

> [@Archinist](#): > > Well, I would assume that the actual components for computing would weigh around 10 kilograms, and the case and accessories would be around 25 kilograms. Of course it might be less than that, maybe around 30 kilograms? Have you done any research at all? With a quick Google search I already found [a 450-watt mini-ITX case](http://www.newegg.com/Product/Product.aspx?Item=N82E16811147131), with power supply, that weighs in at just 4.5 kilograms. Absent any objective information to the contrary, your assumption of 10 kilograms for the electronics - motherboard, memory, hard drive, video card, etc. - seems outlandish; [a heavy mobo weighs in at 2.5 kilograms,](https://www.amazon.com/GIGABYTE-GA-H97N-WIFI-LGA1150-Mini-ITX-Motherboard/dp/B00PM5J5TK/ref=sr_1_14?s=pc&ie=UTF8&qid=1482178602&sr=1-14&keywords=mini+itx+gaming+motherboard&refinements=p_n_feature_six_browse-bin%3A2057509011%2Cp_n_feature_keywords_browse-bin%3A5779376011) maybe add another couple kilos for a video card, hard drive and BD drive. I can’t imagine a suitable liquid-cooling system adding 20+ kilos to this. Go spec out some hardware for the system you want, pin down the weights; I’ll be shocked if you come up with anything close to 35 kilos without bolting slabs of lead to the case. ---

I know that high-performance laptops use around 300 watts, so surely you could build a decent desktop for maybe 450 watts and then undervolt it or throttle it down to around 400-ish watts? With all due respect you’re just gibbering regarding your weight calculations and making everyone waste their time on your 35 kg nonsense weight estimate. Have you actually ever built a PC of any kind? You seem to have absolutely no idea about the real world weight of the total package in this form factor. ---

I, too, am dying to know why this computer is expected to be several times heavier than other desktops, but for now I will settle for a simple question: in a water-cooled system, how much fluid is involved? And is it actually just water in the cooling getup, or water plus some kind of additive? ---

Well I was thinking about putting a UPS into the chassis surrounded by a bunch of high-powered fans and required equipment just in-case I took it somewhere where there were no spare power outlet. The UPS might also go outside the chassis and be bolted into place by an extended steel frame box which would be lightly covered (not completely covered) with a breathable coloured material so that it doesn’t look odd. Since the UPS would be heavy and unbalance the rest of the stuff, then I guess a heavy metal brick or a bag of sand or something could be added to the opposing side, to make the weight balanced. Then I guess either a 12v screen or an old tablet/laptop screen could be inserted into a hinge at the top where a hold could be bored out (or just dented/knocked out since machines are expensive/difficult to hire) and the wires could be run from the PC to the screen. Then you could just knock some more holes into the chassis and rip out some spacing for the keyboard and a trackpad mouse and then just put a piece of paper over it for protection and portability. The screen could also fold down on a hinge. The paper would be normal durable paper, and a roll of sticky tape could rest on the side of the PC chassis at all times, along with a paper holder. Then when you need to use the PC, you simply either plug it into existing perisher pahs or tear away the bit of paper and move the screen up. Then when you are done, you fold the screen down and put the paper over the top, then use the sticky tape to tape it down securely. Then you use the luggage handle and wheel it away. This is what I imagine would be the most efficient, although the feasibility of the screen idea is a bit wonky. I think I’ve seen 12v monitors before, so it shouldn’t be too difficult. I think usually the water loops you buy in walmart for PCs are usually just little bits of coolant stuff that goes round and around in a infinite loop of rubber pipes. The water goes past the metal radiator and probably cools it down and a pump makes it go round. However these are the walmart ones, the ones you can make yourself are usually extremely convoluted and have dozens of different pathways, storage places, covered in LED lights and colored tubes, have lots of leaks if you don’t fix them every 5 minutes and apparently you have to change the coolant every now and then and they’re supposed to be very expensive and difficult to put together but sometimes are slightly better than the pre-built sealed walmart ones.

> [@Grey](#): > > Why do I have this image of a 70s IBM executive showing off a portable computer? My parents had a [TRS-80 Model 4P](http://www.trs-80.org/model-4p/) when I was younger. The “P” stood for “portable”; it was designed to be a single, fully encased unit containing the monitor, CPU, disk drives, and it had a special storage compartment for the keyboard. According to the above link, it weighed in at “only” 26 lbs. “Portable” was an aspirational title more than anything. It was easier to tote the whole system around than a similar system made from separate components, but it was by no means an “on-the-go” computer. ---

A buddy of mine had an [IBM Portable Personal 5155, model 68](https://en.wikipedia.org/wiki/IBM_Portable_Personal_Computer) (or if not that exact model, one that was very very similar) and it was about 30 pounds, with an integrated 9-inch screen.

Is this a deliberate attempt at an impractical portable computer? Because that sounds fun, and I like it - I have mothballed project to make a digital camera that may require two people to carry it. Or is it a serious attempt to make a useful portable computer? Because laptops. ---
