Get money, then get Mac Pro.

Macbook Pro. Or just a Macbook if you can't afford it.

I am going to using it mostly for brickfilming.

no, i did not buy any windows software:)

If you're going to use it mostly for brickfilming, why pay extra for a Mac - get a PC, they're cheaper?

Don't get me wrong, I have a MacBook (I'm typing this on it). We also have a Windows PC, Windows laptop and Ubuntu laptop.

If you still want a Mac, then I would always go for the model one up from the bottom, as the best price/performance ratio seems to be about there. The base models all look a little underpowered.

Finally, do you want portability? The new MacBooks (other than the base model) are more powerful than the equivalent iMacs right now, but the iMac is due an update soon. We are waiting for that before we buy one.

Or alternitavely, you can buy a PC and not have to put an lowercase I before iEVERYTHING iDAMN iTHING

Really, I don't think any of these replies have been very helpful other than richardfrost's. Really we need to know more about what types of things you'd be doing with it. You already told us that it would be used for brickfilming for the most part, but what types of processes do you intend to do? If you're going to be doing a lot of graphics intensive editing for effects and such, I'd say go with one of the new aluminum MacBooks because of the Nvidia 9400M GPU. If you don't intend to really do much more than putting frames together and some basic editing, I'd say go with the Mac mini, which is what I have. The Intel GMA950 integrated graphics chip feels really slow at times, so if you're doing more than basic editing, I'd suggest you should not buy a Mac mini. In the end it is really up to you what you want to buy. Whatever works with what you are planning on doing with your Mac. If you tell us more, we can offer more help for your decision.

I'm going to be doing some greenscreening, and some 3d stuff on it.:)

Well, since you will be doing some 3D stuff on it as well as chroma keying, you'll definitely be wanting one with some more graphics capabilities. With this, you'll need a bigger budget. I'd say go for one of the new aluminum MacBooks or MacBook Pros. The 20" iMac might be enough power, but I'd say either go for the higher end 20", or custom configure the lower end one with more RAM.

For a matter of software, I think you'd be very happy using iWork, Apple's productivity suite, and equivalent (I'd argue superior) to Microsoft Office. Unless you need compatibility with Microsoft Office on other computers, I suggest going with this over Microsoft Office for Mac. My biggest issue with iWork so far is its inability to save Powerpoint files.

For software for brickfilming, it really depends how committed you are to the hobby. If you want to go high end, there's Final Cut Pro ($999) or slightly lower end than that there's Final Cut Express ($199). For effects, it's really up to you. I'm not big into special effects, but I've heard Apple's Shake ($499) is quite good, but there are also alternatives from other companies, most notably Adobe's After Effects ($999). All of these pro effects and editing tools can really rack up a bill, so if you're going for something a bit simpler, I suggest Blender (free!) for effects. I think that the new iMovie '09 should be good enough for basic editing.

Do you have a budget? How much are you willing to spend?
