Scheduled delivery of my parts is 12/5 (next Wednesday). Ended up adding a couple more 500's plus an Xbox 360 webcam to act as my "iSight" - $35 shipped at Buy.com:
http://www.buy.com/prod/xbox-360-live-visi.../202790238.htmlTotal was $1336.65 for: (I already purchased Leopard, but add another $109 - $129 for that if you don't have it)
-2.4ghz Quad-Core processor
-8 gigabytes of ram
-1.5 terabytes of hard drive space
-20x DVD burner with Lightscribe
-Bluetooth 2.0
-1.3mp Webcam
-256mb 7300GT video card
-Firewire 400 + USB 2.0 ports
The equivalent Mac Pro (dual 2.0ghz Xeons) came up to $5115.
My "Hack Pro" is over $3700 less! (really over $3800 less since the Mac Pro doesn't come with an iSight camera, but it does come with a keyboard/mouse so I'll call it even) I will do a detailed writeup of the system and build process once I get everything up and running. So far, here are the only drawbacks I see:
1. The Intel motherboard requires that the second SATA controller be disabled in order for Hackintosh to work, meaning I only get 4 SATA ports. I have 1 SATA DVD drive plus 3 SATA hard drives (primary boot drive, Time Machine drive, and Parallels VM/other files drive), so I'm already maxed out. If I want more storage in the future, I can always go with a PCI controller card or even a RAID card.
2. Boot Camp seems to be a no-go since the EFI is part of the OS X Hackintosh system rather than the motherboard. However, since this is a PC - who cares? I can just dual-boot if I need real performance (instead of a VM). The Crysis PC game is looking pretty fun so I might upgrade to a better video card down the road for that.
3. Future updates will have to be verified online as working on Hackintoshes before being installed. Even though I will be running a vanilla kernel with the PCI EFI hack, who knows what Apple has up their sleeve; a future update *might* break the system, so I'll have to be very careful about downloading updates.
4. I'm limited to mainly 7000-series video cards if I want the best compatibility. The 8800s and some ATI cards seem to be working okay, but the 7000-series has the best track record.
5. The Intel Bad Axe 2 motherboard can only support a maximum of 8 gigs of ram. If I ever wanted to upgrade for whatever reason, I've already maxed out the board. Right now a Mac Pro supports 16 gigs of ram officially and 32 gigs of ram unofficially. A future BIOS update on the Intel board may or may not be able to increase the ram cap - I don't know if that's a hardware or software-imposed limitation. Not that I'm saying 8 gigs isn't overkill already, but since that upgrade was only $200 I can see 16-gig kits coming down in price in the future too.
So really I'm pretty much set, the only thing I have to be careful about is future Apple updates just to be sure they work 100% before downloading them.
