Well, it’s hard to beat the clean aesthetics, quality and worksmanship of Soldam products but there are quite a few good case makers out there. Antec makes nice cases though they tend to be larger.
Shuttle is now making nicer SFFs if that’s what you want. If SFFs aren’t your thing then you may even want to look at the ones that are being touted as HTPC cases. They tend to be extra pricey (usually because of integrated LED readouts) but are also generally roomy, quiet, and better looking than a lot of generic tower cases.
