Right I need some help here, I need some suggestions for something that has the ability to survive to -15C to 35C that is either the size of a Dell R210 or a small form factor desktop equivalent (as its going to be wall mounted literally) has to be 4 core either Xeon, core 2 duo (higher end) or i7, 4 gb of ram and 2 x 250GB SSD in raid 1 ??? Ive had a look at some of the stealth (sorry if thats a competitor but I thought since its specialist area it should be ok) range but they are all 0 - 45C ....
Server to survive -15C ?

i doubt you will find one as it will likely ice up inside etc; maybe you will find something specialist. im going to have to ask..... why? 
edit: what about a normal case with a small fan heater in it
not as stupid as it sounds.

i think you may find that when the computer is running the temp inside wont become that low, as all the components are generating heat anyway.
You'd want the system to be relatively compact, so that it can keep heat in when needed, but also has a couple of fans, and set a custom fan profile so that at, say 0-10 they are not running but above that they run slowly until it reaches 30 or something like that.

you will get condensation, thats probably why the system you looked at states 0 as a minimum......
if you think about it with a sdd, -15 should be ok as there are no moving parts its all silicon / plastic / metal... but I cannot see a way to get round hte condensation...
and at -15 a computer will not actually get that low as its kicking out heat anyway.
I recon condensation would be your enemy here if anyone can think of a way to stop it.....???

well from experience over christmas my amd 3000 went down to 5C in my garage at idle and my energy saving hdd went down to 1C and none energy hdd's were 3/4C so thats pretty sketchy.... As said above the moisture is the biggest threat and Im hoping for an all in one solution with as little bodge as possible, so I dont have to spec out an enclosure etc .... I have found all in one boards etc and atom based temperature able pc's but an atom wont run 2008r2
EDIT:
oh an to stop moisture seal it right up with duct tape

Don't you only get condensation when a gas is cooled by something. The server would be the hot item here, if there's liquid in the form of gas it won't be forming condensation unless the computer is below the ambient temperature of the room.
Personally I wouldnt worry.
Where I used to work we had a warehouse which had computers and a couple of servers in the back. The room at night would plumit to about -15c and in the day be the normal temperature. This was winter summer wasnt a issue.
The servers were left on and were nice and warm (ran very quiet). The workstations turned on in the morning and off at night never skipped a beat.

good to know
and yeah I've had a chat with our premier sales contact over this and he's had to go and check this over ....

You may be able to use some of that paste that people use who use liquid hydrogen to cool thier computers... It's designed to stop condsensation problems...

For external applications we use industrial mini itx (ok they're not servers but hear me out) in a sealed IP rated panel, if it's really bad you can install a small industrial electrical panel heater.
You need to be looking at industrial automation products for that kind of robustness.
If its proper servers you need from a brand (dell/hp etc) then look at sorting a small room out (eg portacabin with controlled enviroment)

You mean a dehumidifier?
A humidifier will increase the humidity.
That might have been what I meant
I have a computer system running at about 1000 feet on the edge of the Pennines, it is kept inside a panel which is inside an IP65 rated enclosure.
Inside the panel is a small heater which keeps all the equipment warm in the winter.
It has been there for several years now and has been fine during the last few winters, not sure of the exact temp it has gone down to but after the last few weeks it was lower than -15 DegC.

hmm just a wild of the shelf idea concerning the Condensation issue, what about going the opposite direction and sub-merging the core components in something like oil or some other fluid matter which has a low/ high freezing temparature.
It could potentially bridge the components depending on what liquid you were using. I would be looking at Marins post.

Dielectric grease and neoprene. It's what I use on my Phase Change Cooled computer. Keeps the cpu nice and happy at -50 degrees C.
