Hello! I'm thinking of upgrading my case - liking the look of the Obsidian 550D and 650D. Having read some reviews, the 550D is quieter, but the 650D is more suited to water-cooled systems, on the basis that the 550D will only accommodate one 15mm thick 240mm rad. SO - 650D. Decent choice? Anyone had any experience building a system like that with a dual-loop cooling setup? It seems to be fairly-priced, and I can get in at least 1x 240mm and 1x square 200mm rad, so it might be a go-er. Thoughts? I'd also looked at the TJ07, but I think it's a bit pricey for me at the moment... Ta.
