What I'll probably end up doing is finish up the foundation this week. Mount and level the machine on the foundation this weekend. Hopefully power it up and test it with the Dynapath control this weekend also and play with it until my linuxcnc parts come in.
Now I gotta think about what I am going to do as far as the PC setup and the driver cards...

The other option I was thinking about was an corei3 dual core sandy bridge setup...

No, it doesn't get along well with flaky video, whether integrated or not. The Intel chip on this board is fine.I understand that linuxcnc does not get along well with integrated video.
It's nothing to do with rt.I understand I shouldn't install more than 2 gigs of ram because of an issue with the real time kernel?
A 32 bit system cannot use more than about 3.25GB of RAM, even though in theory it ought to be able to address 4GB.
The Ubuntu installer was dumping the rtai kernel and reverting to the stock pae one when it detected >2GB, which caused all sorts of head scratching!!!
Don't. Read this thread, don't think he was ever able to get rtai running on his Sandy Bridge MBThe other option I was thinking about was an corei3 dual core sandy bridge setup

After going through the machine, if I want to keep all of the functionality, it looks like I am going to need:
6 encoder channels for XYZ (rotary plus linear scale for each one.) One Encoder Channel for Spindle. Two encoder channels for 4th and 5th respectively. Thats a total of 9 encoder channels.
6 +-10V outputs for XYZ+Spindle+4th&5th
16 Analog Inputs for spindle motor load, coolant pump load and various analog (4-20ma) sensors (pressure, temp, tank level etc.) sensors
A metric crap-tonne (about 30 inputs plus 24 outputs) of various field IO field inputs and driver outputs (lube, air, solenoids, limits etc.)
For the driver cards I was going to use the following:
1x 6i25
1x 7i77
1x 7i85 (Five channel RS422 hub plus 4 encoder inputs)
1x 7i64 (RS422 Interface to 24 Opto Isolated digital input plus 24 opto isolated 2.5 Amp output drivers)
2x 7i87 (RS422 Interface to 8 Analog +-10V inputs plus 3 digital outputs)
I'm a little green on setting up Mesa cards in linuxcnc, does this setup look ok?

That is what I would do.To get around the ram issue, would I run the installer with 2 gigs and then put in the second stick after the install is complete?
Ref the Mesa boards I'll leave others to answer, I haven't used them.
I know John and Andy both use them with a 525 and the only problem I recall is possibly headroom if in an ITX enclosure.

Thanks ArcEye, I really appreciate it. So I should be ok with the Atom 525 on that mother board. To get around the ram issue, would I run the installer with 2 gigs and then put in the second stick after the install is complete?
Just download the latest LiveCD and use that. There have been a couple of fixes to the LiveCD as of late and the 4Gig ram issue is one of them.
Does the D525 have a PCIE slot? I don't recall seeing one... but I wasn't looking for one either. I used a 5i25 in both of my D525 computers.

According to the newegg, it has 1 Mini PCIe, is this not PCIE? Either way I guess it doesn't matter, I would just use the 5i25, I just assumed mini PCIe was the same as PCIE.

Be careful there. The D525MW board has a full-size PCI slot and needs the 5i25.For the driver cards I was going to use the following:
1x 6i25
The DN2800 has PCI-e (PCIE? Anyway, the little short one) that suits the 6i25.
Pretty much the default choice for servo setups. Note that there is a fair bit of field-IO on that board, with enough current capacity to drive reasonably sized relays.1x 7i77
That seems to be Mesa's 8i20-aimed board, but certainly seems like the ideal thing to hook up the extra encoders to and connect extra SmartSerial boards.1x 7i85 (Five channel RS422 hub plus 4 encoder inputs)
Is a very nice card, with some fairly serious voltage and current capacity. I have one on my machine and I like it, though it isn't cheap.1x 7i64 (RS422 Interface to 24 Opto Isolated digital input plus 24 opto isolated 2.5 Amp output drivers)
I am not sure what you want this for, though. Why do you need 16 analogue inputs for? The vast majority of machines have none at all.2x 7i87 (RS422 Interface to 8 Analog +-10V inputs plus 3 digital outputs)
