The latest addition to the P-Series family is the 925XE-based SB95P V2. Although the 925XE chipset was designed as a companion for pricey "Extreme Edition" Pentium 4 processors, it's found favor among enthusiasts frustrated by the overclocking limitations of Intel's other 900-series chipsets. The 925XE has no such limitations, making it an ideal overclocking platform for more affordable Pentium 4 processors and a surprisingly complementary companion for the enthusiast-friendly P-Series chassis.
With a P-Series chassis wrapped around a 925XE chipset, the SB95P V2 could be the ultimate Pentium 4 small form factor system. Read on to see if it measures up.
As always, let's kick things off with a quick look at the SB95P V2's spec sheet.

Apart from the 925XE chipset's support for a 1066MHz front-side busincluding all the bus dividers needed to keep memory, PCI, and PCI Express running in spec at those speedsthe SB95P V2's spec sheet is typical for a 900-series platform. The SB95P V2 is equipped with an ICH6R south bridge serving up High Definition Audio and loads of Serial ATA RAID.
Shuttle bolsters the 925XE chipset's capabilities with the usual mix of third-party codec, Gigabit Ethernet, and Firewire chips. The Broadcom GigE chip is a PCI Express device, which would nicely free up the PCI bus for other devices, if the SB95P V2 actually had a PCI slot. It doesn't, which makes the SB95P V2 one of the first PCI slot-free platforms we've seen.
The SB95P V2's lack of a PCI slot is an interesting twist that's both forward-looking and inconvenient. On one hand, the cube comes equipped with a PCI Express x1 slot for next-generation peripherals. Unfortunately, the dearth of PCI-E x1 cards severely limits upgrade options, at least for now. Until PCI Express audio and TV tuner cards become available, you might find yourself wishing that the SB95P V2 were a little less cutting edge.
