Shuttle has tweaked its SLi-supporting small form-factor barebones PC, the XPC SN26P, just ahead of its release in coming days.

The machine was unveiled earlier this year and dutifully sent out to hardware reviewers for comment. Shuttle yesterday said it had modified the machine in response to feedback.

The SN26P is pitched at AMD Socket 939 processors, which connect to the PC's Nvidia nForce 4 SLi-based motherboard. The chipset brings users 3Gbps Serial ATA with RAID and NCQ, a hardware firewall, gigabit Ethernet and, crucially, the twin PCI Express x16 slots needed to plug in a pair of GeForce 7 series graphics cards and have them render 3D images co-operatively.

To that, Shuttle has added VIA's Envy 24PT audio processor to equip the unit with 7.1-channel sound.

Shuttle didn't detail the tweaks it had made to the system, but it did note that the SLi heat-pipe cooler required by the pre-release version sent out for review is no longer necessary and has been dropped.

The XPC SN26P has begun shipping around the world and should be available in stores in less than one week. ®
