all looks great
as a fellow dual N54L owner - can I ask what rack that is please ?
Certainly! It's the Ikea Lack tables but I've cut the legs down on them. What you can't see on the "blind" side of the legs, I've used small L brackets to fix the legs into position so it won't fall off itself.
What are you using the N54's for? I've got ESXi running my "services" Ubuntu server (Nagios, Cacti, DNS2,) and Windows 7 and the second is running Xpenology which in time will become my backup for the main Node server.
