There are quite a few reviews on the web that can be accessed via Google.
Most owners seem to have them for the abiility to mount a 120.3 rad vertically with the optonal brackets in the right hand side. They are an awsome case and if into Cooling then definitely worth it. However some people will think is too easy and like being able to get a 120.3 into a more normal size case. Me I like the fact is based on wheels so real easy to get to a LAN Party.
You can easily mount Dual PSU, 120.3 RAD, disk drives and even a second smaller 120.2 rad if use the optional roof plate. All of this without having to worry about space or having to mod the case in anyway. (other then changing some plates out.
I am so tempted for a water cooled project using AquaComputer Kit as can mount everything internally and not a drill or dremel required.
I think I worked it out for the case and accesories I wanted was around the £300-350 area.
For that I get the case, the rad mount, 3 x 120mm fan holders to use in front of the rad, the rood rad mount and the dual psu mount. Would be worth every penny as I am useless at drilling etc.
The other case worth considering is a MountainMods U2FO Duality case which is similar size and allows 2 x 120.3 Thermochill Rads to be fitted and takes Dual PSU even two full sized ATX boards if you want. Works out the same price range though and too me doesn'n't look as understated. I like the fact that can hide the fans on the Lian-Li so looks neater.
I have never been a fan of Lanboy style cases with illuminated fans, cathode lighting etc but some people do
