Shuttle XPC SB61G2 v3.0
 

It's a tidy, polished implementation of a well trodden concept, with the odd rough edge here and there. But nobody else
does a Pentium 4 SFF box quite like Shuttle, with the SB61G2 v3.0 one of the best.
A price of just under ?200 inc VAT in the UK should see good sales.

Recommended if a P4 XPC is what you're after and you don't fancy splashing out on the RefleXion or an SB75
