I'm not exactly sure what you're asking. If you're asking if 1U and 2U server units can handle CD-ROM and floppy drives, yes they can. I believe a 2U can handle a standard CD-ROM drive, but for 1U there are combined slim CD-ROM and floppy combinations.
For cooling: the more things crammed into a smaller space will create larger heating problems. Just make sure you have sufficient cooling
The proper name for those small server is 14 inch deep 1u servers. U or Unit refers to the hight of a server not the depth.
So you are asking if you can fit 84 1/2 debth / 14 inch deep servers in a rack. The answer is you can get 80 with proper cooling in the data center. You have to becarefull though as most providers only give you Closed cabinets that are NOT 3 FT deep or 2 Post racks with shelves. You have to use a 4 post rack that is 3 feet from front to back.
Yes they are very good. If you have proper cooling fans in them.
There are models that come with 2 Fixed Disk drives that do not have room for CD or Floppy, but you can also get models with 1 fixed drive that has space for slim line cd rom and floppy drives.
I reccomend the supermicro 14 inch deep servers. They are very good, and their passive cooling works great.
As a host I can't see why anyone would look at these. Only a single disk, very poor thermal designs and in order to power them the extra AC your rack would need to power that many servers would cost you more over a year than if you put in 1U or 2U P4s or xeons.

Yes, it would cost less to power 80 servers than 40 servers... but if you're short on space and high on power they'd work great. How does it cost less to power 80 1u servers than 80 half depth 1u servers?
The main issue with these are heat and power, not price, additional cost, etc. as they'll only save cost, after purchase, if the temperature and power are fine. It may be hard to find someone to give you 80A of power per rack, which is about what you'd need for 80 servers, and then you'll also need to be in a top-rate data center that can cool that many boxes, as the temperature output will be the same as 80 1u servers and in a smaller amount of space.
do not worry about power, since I want to install 45 server in a RACK of 42U, I believe that I will put 30 server 1U and the others in 1/2U. It can have temperature problem? In datacenter they are low temperature all the year old.
as long as the ambient temp is low you will have no cooling issues unless you have failed cpu / case fans in your system.
As far as bad design, the supermicro has a very good thermal design and heat flows out of them nicely. They do fit two drives if you don't have cd / floppy and any host that puts cd / flpy in each server has to be out of thier mind. In my mind they make good sense.
RackLogic.com also offers those 1/2 depth servers, and happens to have some images on their site (or previously had) that Servirack uses on theirs, and so does SimpleRack.com (See http://www.racklogic.com/images/photos/pic7-lg.jpg - I believe those photos were from UnitedColo).
