When you first look at the new Thermaltake Level 20 HT it would be understandable if you had a flashback to the Level 20 XT that we covered in a four case round-up HERE. The Level 20 XT and HT are both huge, cost around £200 and have glass on every visible surface so it would be perfectly reasonable to wonder why Thermaltake developed the Level 20 HT, and happily we have a simple answer. Despite the family resemblance, the Level 20 HT uses a completely different design with air intakes at the bottom and a rotated motherboard tray that puts the rear I/O in the roof of the case.
