orcishgamer: I actually like Lian Li cases, but it's hard to recommend someone spend 200 dollars on their case...
I love CoolerMaster cases. Lian Li makes awesome stuff, but you can buy a barebones kit for the price. Coolermaster gives you plenty of space, fans, bays, etc... and are built amazingly well.
You know... everyone keeps saying building your own is easy... and it is. Insert Tab A into Slot B. It is easy. Clean wiring takes some finesse but overall it isn't hard.
It's designing a PC that's hard. You can just grab a mobo and some parts and whip it up. I took four weeks to buy my last PC's parts... and 2 hours to build it.
(Why 2 hours? I spent over an hour on attaching a heat sink the size of my head with only two hands... I should have called a friend to help, and the heat sink would have been on in 5 minutes)
There are lots of good parts, but some play well with some others better and vica versa. Getting the right RAM and CPU and all that takes research and learning. But once you've invested that time, your computer savvy and ability to tune, tweak and troubleshoot goes way up... and each new build gets way easier... so it is worth it.
