This odd little concept is a new way for securing a hard disk in a computer. The drive sits on rollers, so that it can be quickly and easily slid in and out of a case, and is then secured in place using velcro.

We've not seen this before, but it's being used in the new Zalman Fatal1ty case that comes out this summer.

Aimed at gamers, the case is made of thick aluminum, and uses five fans (complete with red LED's) for cooling.

You can get it through Quiet PC, and owner Glen Garrett admitted the noise it makes doesn't fit with his ethos of selling products that make computers quieter.

We spoke to him at the Computer Trade Show in Birmingham, where we spent the day chatting to various components manufacturers and distributors.

Other Zalman products included a low-cost cooler, aimed at the enthusiast on a tight budget, which comes out next month.

Costing about £20-£25 (the final pricing is yet to be set), the CNPS8000 uses heat pipes as well as a fan to cool PCs.
