Windows 7: Going to build a pc, the common question - i7 vs i5!

1. Don't worry about the RF.
2. Use a motherboard tray, mounted squarely so the motherboard is not twisted.
3. Use what ever cooling you like but to be quiet use Noctua fans
4. Ground your mother board tray to the black ground wire from the power supply and to the power supply case. Everything else will use the motherboard ground when they are wired to it. (Plugged in) Anything that is plugged directly to the power supply will be grounded using the power supply ground.
5. No matter what you make the case out of the cooling, air circulation for cooling principles are the same. Selection of wood I would like birds eye maple for mine.

Cripes Bear that sounds expensive the birds eye I mean - not that I think it is not the nicest I suppose if cost were no barrier then some real nice ebony wuld be one of my choices but I don't think one can go past Huon pine it is so easy to work - I have done a few pieces with it and it machines and hand works like nothing else. In fact I would liken it to working a surface akin to carrot.

It is VERY expensive these days though after they used it a great deal for whaling boats in Tasmania.
Huon Pine Tasmanian timber

Huon pine Island Specialty Timbers < take a look at some of these the King Billy and Celery top pines are also beautiful.

The shielding is or would be to me a secondary consideration really and the cooling well I did go on bit eh but thats just me I can't help but get overenthusiatic re those things

Whoa, slow down guys.

Statistical data actually does generally show air cooled systems living longer lives. (though honestly this is really just due to the fact liquid systems have more moving parts.)
liquid cooling can only really show off in extreme overclocking situations.
In said situations it's usually the better though.

I'm a bit old school so I never really adjusted to the idea of having liquid in my computer.
I've built several systems for others using it, and they're all very happy though.

Also Air is generally cheaper.

Wow, a lot of interest, thank you all for the input! Ok, firstly with the mobo backplate. I will get hold of a backplate and screw that into the wood. As for grounding, I can get that sorted now, thanks for the tips! I'll ignore shielding for a start and then see if I get affected by it!

Now for cooling! Yes LN is only used on rare occasions, although it's actually quite cheap! (about the same price as milk!). But it does damage a lot of parts! I'd never go liquid cooling in something I built I'm afraid! It's just me! It is true that heatpipes are hollow and contain a heat transfering liquid. This liquid (from what I've learnt) absorbs heat, evaporates and rises. Thus transfering the heat up the heatpipe. I don't know how it works with the cooler on it's side! It probably just moves towards the cooler part of the cooler. Cooling wise, several fans I think plus a noctua! I won't have a graphics card although will make it easy to put one in so will just make sure I have space! I may possibly want a tv card or a sound card, haven't decided yet!

As for the case material. I hadn't decided this yet either! I was considering maybe walnut of some sort but that maybe a bit dark! The other one I was considering is oak. I quite like the colour and think it will fit in. Will have a look at the other suggestions, thank you very much for them!

Anyway, thank you all ever so much for your help!

Your wood project did remind me of this guy who actually has his own site and makes these things now.

Hey MG the heat pipes work virtually in any position I would think except upside down and the fluid is water - de mineralised / distilled water call it what you will.

Heat pipe - Wikipedia, the free encyclopedia < I know it mentions other fluid materials but I thinkin the main computer stuff is water.

I will mention laptops here because they employ the same system of heat transfer in those pipes and well you don't have to be Einstein to work out what position they are in unless you are a circus performer LOL!!

I was going over the top and mentioning extremes of course when I prattled on about the LN2 One could go further than that and include liquid Helium but my only concern was from the beginning was that wood is quite an effective heat insulator thats the only reason I even got into the heating debate. Personally I chose liquid this time because of the neatness of the set up otherwise I would have gone the Deepcool and would have had to work around fitting the RAM somehow.

I suppose I had better butt out at this point as I am probably causing more confusion than order. But before I go do have a look at those Tasmanian woods mate they are just something else. I come from the UK originally and have worked a lot of different woods in my time but these are just simply magnificent to look at work and the Huon and Celery pines top are so very light too - weight wise that is.

Anyway good luck

Please don't go! I've been enjoying the cooling information, I've learnt a lot! I'd realised it was extreme, I think we all know I won't be nitrogen cooling!! I've actually just been looking up phase change cooling, apparantly it does happen! I'm afraid though, I will be sticking with a boring air cooler, I'll just get some low profile ram. I'm a bit of an air cooled fan, for cars too in fact! So you will do well to persuade me otherwise! As for the heatpipes, I still don't see how they would work if they are horizantal. Of course they would work but wouldn't the be much less efficient than if they were upright? Surely we are working on the convectional current principle? Or am I missing some fundamental physics law (probably am!). However, this would explain the reason why my laptop's CPU temps rocket when I lean it back so the keyboard is vertical. Also, do you really think it is distilled water? I understand it's non conductor properties due to it not containing any ions. However, surely it's evaporating temp would be 100*C and a heatpipe will be lower than that? Or does the water just not evaporate and just moves via convectional currents? I'm just letting my brain run wild here!

And thanks for the tips on the wood, I'll look it up! The problem with oak is that it could weigh a tonne!!

Anyway, thank you very much, don't know how we got from me making sure I wasn't overkilling with an i7 to what's in a heatpipe but hey, it's certainly not a bad thing!!

Well the answer is really in the Wikipedia ref. Liquid of whatever material is heated inside the pipe and turns into a vapour lets say very much like in a kettle now that vapour is therefore an expanded state of the liquid and will escape to a place of lower pressure (denser material and therefore heavier) ie the top of the kettle by rising (hot air a good example) and pressure differentials.

Now in the cooler tubes this also happens but is aided by the fact that there is a wool like copper material inside the pipe that also provides for capillary action which aids the transfer of the vapour to the cooler end of the tube. The then cooled liquid then returns by the same process ( becomes denser once again) to the CPU heatsink end for the process to start all over again.
It reminds me of when I was plumbing with my father when we installed gravity fed hot water heating systems the hot water flows upwards to a tank then cools by convection and the then slightly cooled water ( has become dense again) returns to the heater device to be reheated thence to be sent to the tank once more. So you see it is really a continuous loop.

Now the only problem with computer coolers in my mind is the use of aluminium as the cooler fins for dissipating the heat as it lags significantly behind copper and silver which I know is prohibitively expensive to use in conducting heat. But it is of interest that most of the laptops I have ever stripped down have copper cooling fins and myself would be willing to pay a premium price if the fin in ordinary coolers were manufactured from copper.
Steel: 50
Brass: 109
Aluminum: 250
Gold: 310
Copper: 401
Silver: 429
Interestingly enough diamond is also a good heat conductor and I have used that nano diamond thermal compound on occasions but have neither the proper measuring equipment or time to test it out at home.

See this Q & A: Best heat conductors | Department of Physics | University of Illinois at Urbana-Champaign

Anyway I am spoiling your thread and really it wold be nice to discuss it in a thread of it's own as this subject is of great interest to us all - so I shall stop here before everyone goes to sleep.

Hum Bear I seem to remember some time back and I think it was in here - building a colossal wood based build, and I cannot think what became of it. I am sure the fellow was from Canada? I am sure it might have been in show us your rig. There were lots of pics of the different stages including his garage / workshop where the wood was assembled
