1.6GHz single-core Atom, i945 chipset, and the thing would've EASILY been fanless had they not used the Intel chipset.
10/100 LAN (no gigabit,) and PCI (not PCIe) for more downsides. (They wouldn't affect my use of it, but...)
Then again, the price is right... the most expensive places want about $100 for it, and I see mini-box is listing it for $80 (but they're out of stock...) This thing is gonna thrash VIA.
Now, if they could just make one with a fanless chipset and a dual-core Atom... I'd rebuild my server. (The Celeron 1100 is getting just a bit long in the tooth...) Don't suggest the D201GLY2 - that thing wasn't designed for fanless applications, it's for when there's a case fan powerful enough to cool everything.
RAID support would be nice, too (not sure if the D945GCLF can handle RAIDs.)
