Reddit reviews Reliable Hardware Company RH-12-SRR-A Rack Rail

I got the rails on Amazon. They're pretty sturdy though one piece to another set I bought later did have a flaky paint job http://www.amazon.com/gp/product/B00JQYV8BQ/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B00JQYV8BQ&linkCode=as2&linkId=IBSCPXGPANCE667E

Have you experienced any spacing issues with those round-hole rails?

I built my own 12U wooden rack and used these.

The spacing was so bad I only had 6U of usable space.

I picked up a 24U Dell rack with square holes for $70 and threw sides and roof on the wood rack and it's now a doghouse.

I bought them from Amazon through reliable hardware I believe.

I regret not getting the square slots though. I'll find the link for it and edit my comment.

A little more expensive for easier mounting, flexibility and compatibility. The cage nuts give you a bit more leeway if your rails aren't mounted 100% perfect.

e2: These are what I bought specifically, but I would still recommend the starcase square slot rails.

You could always do what I did, but a smaller version, and wall mount it. I picked up a set of 12u rails from Amazon (they have smaller and larger versions available), then just built the 'chassis' out of some cheap pine wood from Home Depot. ;)

Nice wood working, rack looks real nice actually. If you want it to have real rail sidings you can buy these, work real well. https://www.amazon.com/dp/B00JQYV8BQ/ref=sr_ph_1?ie=UTF8&qid=1485093027&sr=sr-1&keywords=rack+rails
