I've done it Matt. It's not as bad as it looks once you get in there and get comfortable, it's like any other computer. Just take your time and use the excellent walk-throughs on iFixit. The only advice is to take note of how all wires are routed during disassembly and route them exactly the same way before reassembly so that they don't get pinched and/or broken. Also, make sure you have the right screwdrivers, torx bits, etc. It can be an exercise in frustration trying to use flat head screwdrivers to remove the torx screws (although possible).

It's really no more difficult than any laptop, except the parts aren't always as accessible without a little work. Also the connectors simply lift off and on, so there's nothing really to worry about there.
