I've always have wanted to get a Mac mini but I can never afford one. I have a credit limit of 300 on my card so I'm going to use it for building a hackintosh. I have most of the parts but the few main parts needed to build it.

Motherboard
CPU
Memory
OSX for Intel (Universal)

I have found the parts and the motherboard even has the TSP chip that Apple and Intel both made so I don't have to use a modified copy of OS X. Just have to use a 3rd party bootloader to force boot OSX or get a hold of a intel mac and do a ROM dump and force flash the BIOS on the PC and it will be a full fledge mac by using EFI instead of BIOS. Thing is it's not all illegal since this is the same hardware that Apple uses. Since Apple buys their hardware from Intel technicality I can build a mac with out the middle man of Apple. All I have to do is buy a legit copy of Universal OSX and it's alright.

Motherboard
1GB DDR
CPU

In the range of $286.00 before tax. The CPU isn't a Core Duo but it will work just fine.

So why aren't there other companies selling computers like this?

The EFI system is the reason why. Also you need a licence to sell OS X. Apple can still slap a cease and desist on 3rd party hardware developers. I doubt Apple would take me to court for building a hackintosh but they could if I was to market it. Also I wouldn't be able to get support from Apple on my system but I know enough that I wouldn't need Apple's help.

When you get down to it all you need is one part that is Apple certified for it to fall under the EULA. For a example if I was to use a Apple certified hard drive or DVD drive I would be safe under the EULA.

If you were to build a Apple G4 sawtooth's from scratch and use the sawtooth logicboard and use a 3rd party CPU like from sonnet, memory from PNY, A DVD drive from Pioneer, a hard drive from Western Digital, a video card from MSI and a 3rd party mid size tower ATX case with power supply would this still be a mac or would it just be a PC?

Thanks for the info. So basically apple doesn't want clones to be sold and will do anything to make it not happen

Back in the 90s there were mac clones and Apple put a stop to it because the companies were using copied software. Meaning by copied software the Firmware or back in those days the ROM were Apple's property. The same thing almost happened back in the 80s with IBM but AMI reverse engineered the BIOS system. 

The celerons don't work good with that good with the hacked OSX... lol, I used a Dual 2.4GHz Xeon system, and it seemed to work slightly slower than a low end Mac Pro(Quad 2.0). The Celerons I tried, one wouldn't even boot and the other was VERY slow. Both with nice motherboards. 3.04GHz Celerons or something close to that...

Is hypermicro a trustworthy site? I did a google search on that motherboard and did not get a lower price than 1,000. If you only have 300 to spend on a whole system, I would hate for you to loose 100 in a scam. Defenatly use a Pentium 4 over the Celeron.

I have to agree about the Celeron.  They aren't nic named the gutless wonder for nothing.  They are only suitable as browsing and email systems.  VERY limited.

Go for a single, or if you can afford it, dual core Xeon. You will see MUCH better performance from it.

echebon, I don;t know where you have been looking but on pricewatch.com they range from $99 to $349. I bought a few parts before from Hyper Microsystems and they're alright. Most of the time they sell refurbished parts. They have been with pricewatch since 98.

I've ran a OSx86 system before just to try it out but I used my gaming PC. It was 100 times faster then my sawtooth. I think the Celeron would be plenty. The parts I listed work with out patching or hacking OS X. All I have to use is the Darwin bootloader and the rest is just gravy.
