You can never go wrong with a Lian-Li....
1) Case size and features to fit any taste
2) Anodised Aluminium
3) Build Quality second to none. NONE.

I have the PC50-R for over a year now and don't to excited as it might disappoint you in some areas. Now don’t get me wrong it’s not a bad case by any stretch of the imagination but there are a few annoying areas that Lian Li need to improve.
Good
- Ultra light, very easy pick up and move about
- Very good sturdiness for a aluminium case
- Loads of cooling and standard case fans a very quiet
- Great design features like the expansion slot clips, hard drive cages are all tool less
- Lots of cable management holes
- Huge CPU cut hole
- Dust filters are everywhere, even the PSU fan hole gets one
Bad
- The side panel doesn’t come on or off easily, in fact the metal tab on mine has buckled.
- You will need a PSU with long cables or extensions to take advantage of the cable management holes
- Fans rattle against the metal frame causing vibrations
- Spinning optical drives causes the case to rattle and vibrate
- The front drive bay covers don’t always clip back in place so I have to line them up loosely and leave them alone
- No fan controller
Ugly
- None, this is a great looking case and very functional but if I had to pick one it would be the price as its a lot of money considering the imperfections.
If it weren't for the side panel which is a real bug bearer for me I would be over the moon with the PC-50R and could over look the other minor drawbacks. Prior to the Lian Li I had my previous case for 5 years and side panel was so easy to remove and put back on again so it's strange that a company like Lian Li couldn't get this right given Antec were getting this right years and years ago. As for the rattling I think you can stop that IF you use screws to hold in the hard drives and DVD drives, the tool less clips to hold the drives in place don't hold them tight enough IMO.
