Create a Space limited build room

Hi all,

I am looking to build a config room for a new company i am starting, i have limited space but really need it to be able to cope with around 50 units (either pc / small server). Ideally it would be KVMed so that multiple users can access all the units.

Any suggestions where i can find small racks, sugguested kvms or anyone who has already done this and has a design knocking bout would be great

Also any suggestions / pitfalls i should watch for would be helpful

Thanks in advance
