Generally speaking (and are there any notable exceptions?) do most colo facilities allow you to mount machines/ equipment front and back of a quarter/ full cabinet if required, assuming the depth is available. What depth is a 'standard' colo rack - 800mm? is 1000mm common?
I realise this might disrupt hot isle / cold isle schemes, but basically we have a chance to buy some shallow (ie not deep!) 2U servers in place of 'full depth' 1U pizza boxes.
Any thoughts / observations? All welcome as ever...
Bad idea. Premature hardware failure from the clearly sub-optimal airflow will quickly negate any initial cost savings.
Go to Dell and get yourself some PE860s/R200s. You'll save so much money in the long term .

The particular servers we are looking at (they have weird telco cards in) are better suited as 2u - we arent just being greedy and trying to get more in :-)

How much does one of them boxes draw then? The quescom's we host have minimal draw.
Generally a bad thing (tm) especially if the inputs are on the rear it will become a real PITA to manage. For the cost of space nowadays, it really shouldn't make that much of a difference
I know when I used to manage the Opal Data Centres that I didn't allow this, but then we were more into doing managed facilities as opposed to letting people run free
2x 2u servers in 2u (front and rear)
or
2x 1u servers in 2u (normal installation)
I dont get it?
Key aspects are
- you can fit a standard PSU in a 2U so you'll save £50 ish over a 1U
- 80mm case fans are usually going to push more air arround than two or three 40mm
- you're able to accomodate a decent size heatsink and fan on the CPU.
- no probs fitting mobos with high rear panel sound connectors.

It significantly reduces the wroking life of the equipment due to heat related issues as back-2-bck's are venting their exhaust at each other.
The minimal saving in space costs are more than offset by hardware replacements and downtime issues.

Unless you're running Deltas, 80mm fans aren't going to push more air than the 40mm fans is a proper server case.
Heatsink and Fan? Are you nuts, heatsink fans are one of the biggest causes of server failure in our experience, out of all the server failures we've had since we started, 80% have been down to heatsink fans - 1U + Passive + Redundant Chassis fans = reliable
Sound ports - don't try and use cheap desktop motherboards then
