Welcome to LinuxCNC.org

First of all before I get into hardware I would like to ask, what is max interval in the latency tests?
I know the lower the jitter number the better. What about for interval, is it also better the lower the number?

Now to the hardware part, I found a used Intel Atom 330 board with 1gb ram for really cheap and I have a feeling that it performs alike with the D510 and the onboard video.
Although the onboard video is slightly different for both, they seem to perform the same.
So in this case, I would get the Atom 330, but correct me if I am wrong.

And the D525 seems to be just like the D510, but performs a little worse with EMC2.

On a side note, if I do get the Atom 330, what PSU and case should I get? How many watts would be stable enough to run EMC2?
Is it good to dual boot windows and EMC2?

Are SSD hard drives to any advantage when it comes to EMC2?

And for keyboard and mouse, should I get PS/2 or USB?
Thanks.

60W is plenty with an SSD.
Less power, no moving parts to get damaged by dust or vibration. 8GB is plenty for a LinuxCNC installation, but might be a bit tight if you want to dual-boot Windows.
USB.

Well it was on ebay, and I got outbid. Auction won for $50 plus shipping. Not too cheap, and I do not think that was that great of a deal, but maybe it was and I kinda still wish I won it because it was with 1GB ram. Correct me if I am wrong.

I asked the PS/2 vs USB question because maybe PS/2 would perform better latency-wise than USB because I heard problems with USB, but I guess not.

Also what is max interval in the latency test?
Is a bigger value better or is a smaller value better for max interval?

I know for max jitter a smaller value is better.

Now I am stuck, I want a hardware setup for under $175 with Ram, HDD or SSD, case and PSU included.
8GB of and SSD? Is that enough to run projects for cutting?

For your reference I will be using a HobbyCNC Pro 3/4 axis driver board.

Thanks.

I think it is just thread-period + latency. So it only really depends on what thread period you have set.

8GB is plenty. I _develop_ LinuxCNC on an 8GB SSD. The base installation is user 4GB.
Do you need a case? My board sits in the same box as the stepper drives. Treat it as a component, not a PC.

If you already have a 12V supply (or can derive one from the stepper PSU) then look at
www.mini-box.com/Intel-DN2800MT-Mini-ITX-Motherboard
That has a 9-19V power jack, so saves the cost of a PSU.
Cheap 8GB SSD, as used by me for the last year or more with no problems
www.ebay.co.uk/itm/150593568661
(that's ebay.co.uk but as it ships direct from Hong Kong, that shouldn't matter)
Then 2GB ram is $10.

So I guess that was an okay deal on ebay? It was like $60 shipped. I wish I did bid higher. Only reason I'm concerned is because that board has a super good latency and I did not get it, still thinking about it.

Onboard PSU? Nice, but you sure that would give the entire system enough power if I add drives?

That SSD you linked is a Chinese made SSD. Those are really reliable?

I mean I can get a 32gb SSD for $50 on newegg.

Can you post a picture of your case please?

Thanks.

My sample of one has been. But at that price the Newegg one is compelling. Though you don't _need_ 32GB. The DOM form-factor (just plug it in to the SATA slot) is convenient too.picasaweb.google.com/lh/photo/OT4lV-DVGZ...pFm0?feat=directlink
The PSUs and D510MO are actually mounted on the back of a touchscreen monitor.
