we use Rittal which are very sturdy and they even design 42U cabinets with 10U private lockable. APC are nice and usually seen everywhere nowadays, but we have found that APC are flimsy compared to Rittal.
As for Rittal cabinets. The most common version used in DC’s is the TS8 and this cabinet does have a design limitation when it comes to DC server cabinets. There is a gap between the front of the cabinet and the 19” mounting rails that allows hot air to recirculate back to the front. While the size of this gap varies depending on where the front rails are positioned, I calculated that the minimum open area is equivalent to leaving out a 1RU blanking panel. There can also be a very large gap at the top and bottom of the rack which will cause recirculation.
I have seen one DC where the RFM made sure that blanking panels were always fitted but due the mounting rail positioning the gap was so large that a young lady was able to put her hand around the side. I can still vividly remember the look of shock on his face when it was pointed out to him…. with the CIO present.
There are a number of solutions to this problem from both Rittal and Third party suppliers but I feel that the best solution is to not use this series. There are other series from Rittal that don’t have this design limitation, but they are more expensive.
Well i think Server Rack Package1 will be sufficient for your requirements for other information visit this site: //65.18.175.49/onlinecatalog/server-rack/wrk/network-enclosure-cabinets.htm

Quick and dirty solution, take an 8.5" x 11" piece of paper and cut it into thirds, long-ways....two pieces of tape and done. If you don't want to use fibrous material, talk to your a local plastics plant...you can get some cheap material.
The main goal there is to hold back hot air...so the material you use doesn't have to be a 1/4" steel plate...just the rigidity of paper.
By using paper on my gaps and making a cellophane ceiling, I reduced my upper rack temps 6 degrees at a ridiculously low cost.
They recomend you consider the following:
1) Server Rack Cooling - Fully Perforated Server Racks or Fully Sealed Server Racks
2) Server Rack Power
3) Appropriate Size
4) Physical Security
