Hi Ross,

So right now, I'm thinking about:
- CPU: Xeon E5, maybe 2 x E5-2670/90, for a total of 16 cores (32 threads)
- Hard drives: 500GB, 1 TB or 2 TB (ideally with RAID if it can speed up the
builds)
RAID-5 seems to be what i am after.
Hi Chris,

Isn't RAID-5 going to be slower, especially if it's software? RAID 1
is probably better as you'll potentially double the write speed to disk.
I use a couple of Vertex SSDs in RAID 1 giving a theoretical write speed
near to 1GBs. Write endurance is possibly a concern, but I've not had
any issues using them on a local build machine. I would probably look at
some higher end models if I was going to run a lot of builds. A lot less
noise than hard drives ;-)
Thanks for the info, i will have a look at RAID-1, as you can see, I know absolutely nothing about RAID! ;)
Did you see my correction to this? I meant to say RAID 0. Sorry for the confusion.
No problem, at least it forces me to look at RAID-5, RAID-1 and now RAID-0, thanks! ;)
Sorry, my setup is a RAID0 striped SSDx2 configuration as well, not RAID1. I have a 3TB standard drive for performing backup, since I can lose data anytime, if any one of the drives fail.

The cooling solution is from Corsair, and it's easy to install.

I think, CPU motherboard, SSD, RAM, case, power supply, etc was well within USD$ 1500.

The apple display was the most expensive component.

The Mac Pro, when it comes out would be a perfect build server, though, with PCIe SSD, XEON CPUs, etc.
