How hard is it to build a MacPro?

many used Mac sites are good

Unless you are planning to only run Windows on it, then you can't just upgrade the graphics card with any card on the market. You must either buy a Mac specific card, or flash the firmware with a patched one (check out Cindori and netkas's threads for that). This is because Macs don't use a BIOS; they use EFI instead. You need a graphics card whose firmware is EFI compatible, which none of the ones built for PC's are (currently).

Even if you flash the card, you still need OS X drivers. Unless Apple has released drivers for the specific card you want to use, you're out of luck. And even if they do have drivers, there could be compatibility issues (though I believe these are mainly due to the flashed firmware being incompatible with the specific model of graphics card you might have).

Otherwise, hard drives and RAM can be easily upgraded.

 

I wouldn't go any older than a 2008 Mac Pro (the version before the current version). They have compatibility issues.

If the motherboard are processors are still working, it's not a bad idea. But if either the motherboard or processors are not working, and you don't have a cheap source for new processors, than it's not worth it.

 

Follow a hackintosh guide that teaches you how to build one. It'll be much more usefull.

 

I also agree with a hackintosh guide or some sort of guide.

Some techies have no issues because they can simply write their own drivers. But for the vast majority of us, if it can't be plugged in, downloaded, or bought second hand or from a third party maker, then you are out of luck.

That being said, a techie site would find what you are attempting as basic child's play so it's all relative. This is a great Mac rumors site and general use site, but it's not a technician's site.

That would be more for a www.experts-exchange.com or similar site. I discovered that site before Macrumors and there are people there who can answer anything computer related.
