So other than the mounting holes, there's no difference ? (I couldn't tell if you typed a response which got edited out). I see 01 in stock at wiredzone (Supermicro MCP-290-00001-00 4U Mounting Rails Kit for SC748 Chassis) as well, which would likely be the most convenient option for ordering.Edit 3
They might only send to Germany/EU, let me know if you need help with that.
Also, it seems they have 3 square mounting holes (to fit the server), the 01 seem to have only two (on some pics, 3 on others...)
3 holes 01

I'll order the 01 part from wiredzone and report back. The mounting holes are for the rack, right ? i.e., The holes don't affect the server directly, right ? Since I don't have physical access to the lab at the moment, I am not able to manually inspect the server or the rack.Well I did a lot of edits while checking the differences.
I think 2 vs 3 might be the major issue (whereas getting the 3 hole version might be more compatible then the 2 hole one (check your server though), also it might that the 14 contains some handles for the desktop to rack conversion of the 748 (MCP-290-00001-00 Supermicro 4U SC748 Chassis Rail Kit (Includes Side Handles) - Rackmount Rails - SuperBiiz.com)
