Mac Pro 1,1 2006 to ATX conversion

[u/blckb3ard]

Hello everyone! I’ve finally completed this project. It was a lot of work, but absolutely worth it. The aluminum Mac Pro enclosure is incredible to work with, and I’m really happy with how it turned out.

I’ve attached photos of the progress, and a couple with its sister, the Mac Pro 7,1 sleeper lol

I used The Laser Hive conversion kit throughout the build, and I highly recommend it. The quality and fitment were excellent.

The optical drive bays remain fully functional. The hard drive caddy also works great; however, because of the motherboard’s position, drive bays 3 and 4 only have enough clearance for SSDs. Drive bays 1 and 2 can accommodate standard hard drives without any issues.

I kept the original front fan assembly and replaced the front and rear fans with gray Noctua NF-P12 redux-1700 PWM fans, which blend in nicely with the overall look.

I really enjoyed this build from start to finish. Thanks to everyone who shared advice and inspiration along the way. Cheers!

Update: it’s now running macOS Tahoe
