I've seen so many wall mounts for the iMac, but I'm having trouble finding a mobile cart that will hold the 27". At a little over 30 lbs, the 27" isn't supported by most carts (or don't list the wait limit). The couple that I have found are well over $500. I'm really looking for a simple, mobile cart to hold my new mac; preferably a pole cart or ergonomic cart that is adjustable in height. I know I'll have to buy a VESA conversion system. Some of the LCD TV mobile carts look great, but they don't mention if they support the 100mmx100mm VESA system. Anyone have any suggestions? Any help would be really appreciated!
