Rack mount confusion

I have purchased, from a friend's employer who is liquidating their server farm, a rack-mounted server. I don't have the item yet, but am getting my rack and accessories ready.

So I bought a 12u Kendall Howard wall-mounted rack. It's the standard 19 inches wide and it's 18 inches deep. It has lots of threaded holes on the front vertical rails for mounting servers & accessories, but none on the back.

I go to mount my rack-mount keyboard/LCD unit (courtesy of Ebay) ... and it has ears on the front and the back ... and it is 25 1/2 inches deep. So it won't fit.

And I'm looking at a Tripp Lite UPS and it is listed as 21.5 x 15 x 7.5 ... but a 2U device. So it won't fit and 7.5 inches is more like 4U than 2U.

Did I buy a junk rack? Or is the xU standard not a standard at all?

Thanks for any help!

So ... how deep should it be? And should it provide mounting holes on the back as well as the front?

I see ... many of the 17.7 or 18 inch cabinets say they're for "network peripherals". But some by iStarUSA call themselves "server rack cabinets" at 450 mm ... which comes out to about 17.7 inches.

But others range in depth from 31.5 to 39.5 inches.

And nothing sounds like it will properly mount this Keyboard/LCD I got that's 25.5 inches deep.

So ... how does one go about getting compatible hardware in this stuff?

Thanks to all of you for your help.

I think I'll go with a HP S10614 14U Mini Rack Mount Server Cabinet that I found used on eBay that is 30"(H) x 24"(W) x 35 5/8"(D).
