Hey, do anyof you know where I could buy an ARM computer?
 

Apparently there are these things called computer 'arms' that let you move the screen around and that totally messes up my search!
Is there a good comany/store for this?
I also don't want it to be a small toaster computer, I want it to not be a embedded but normal minimalistic desktop, But if all you can find is a basic embedded that would be ok too.

PS I don't want to buy in bulk, just one. Hobby!

There are many ARM based boards available. The raspberry pi is an awesome new board of this kind, very cheap and quite powerful, but you'll have to wait for it two or three months.
Other options may be BeagleBoard, PandaBoard and Mini2440 - all depends on your budget and on your requirements (peripherals, computational power, network, display etc.)

Would like budget ~30-50$ but at most 100$ (this is just a hobby).
Raspberry Pi looks good but I'm impatient right now, any other really cheap options?

A P4, as second hand, is a better alternative? (pricely)

Monitor CRT is nearly for free.
So, what is your target with an ARM?
(I had an AMD K6-III and bough a P4 3 months ago. Im happy with it).

What do you mean by target?
I want to run Debian with it if that's what you mean (or NetBSD if that doesn't work out).

Check out trimslice. Fit-pc are their x86-based devices, trimslice are their arm-based devices.

there are hundreds of single board computers and lots of arm chips out there
BUT!!!! and this is a big but for you
none of them coast less than $100
even the chips for the smallest single board coast more than you want to spend
