"From A to Z the Zalman MS1000-HS2 is thought through really well. The nice design, the hot swappable drive functionality, cooling design, placement of the PSU, securing PCI card outside the chassis, rubber feet, noise insulation, gaps in motherboard tray for CPU cooler access and cable management, washable dust filters ... and the list goes on. Next to that, the chassis is heavy and sturdy and this editor likes that. Cooling wise the airflow created by the fans is more than sufficient for any setup really, the noise levels are quite low as well.
Any downsides then ? Yes sure, we felt the swappable drive trays are rather fragile. If a HDD gets stuck and you have to use a little more force, the handle just might break off. That seems a little flimsy and something Zalman will need to look at with future models. I very much would like to suggest metal based slide in trays here."
