Thermaltake has recently added another chassis to their Urban lineup. A modern update of the classic Lanbox Lite chassis (also by Thermaltake), the Urban SD1 is designed for builders that are building around the mATX/mITX form factors and still want room for large graphics cards, AIO liquid coolers and multiple drives. Utilizing modular internals in a chassis not much bigger than many ITX boxes, the Urban SD1 promises an easy building experience. Weighing in at 5.8 kg and with dimensions of 239 x 280 x 456mm (HWD), will this sophisticated relative of the Lanbox / Armor A30 deliver on its claims of high-performance in a micro-ATX form factor? Benchmark Reviews was given an opportunity to build a system in the Urban SD1 (model CA-1A9-00S1NN-00), so let’s see what changes have been incorporated in this new member of the Urban chassis family.
