Even if you add something like a Crystal Broadcom card? I read about one guy doing that and he was happy with the results. Actually the writing is on the wall. I think a Sandy Bridge in maybe 3 months or so would be a much better decision. A new computer is more of a need than a want right now.
I do like that ZBOX with the Celeron SU2300 though, just for its compactness. Looking forward to the review.
