re: Just played my first game on the new comp...

it just depends on what your needs are. I don't know what case you have currently, what size mobos it supports, how easy it is to disassemble, how many 5.25 bays it has, etc. If you find out that it has all the space/features you need and a look you're okay with then go for it. My experience with older prebuilt units is that they are very difficult to disassemble without breaking brackets etc.

If you do decide that you need a new case, there are a lot of options that will let you pretty much customize features vs size vs silence that don't cost an arm and a leg. If you want to discuss a potential ground up build or an overhaul please do so in a different thread.
