Well who knows whatz gonna happen .... lot of speculation in that thread and if I was some of the posters, I'd be going back and doing a lot of deleting to try and avoid potential litigation.
Unfortunately, there is no real alternative to FCPU.
PerformancePCs still has a 6.00 resellerratings.com rating, does not have bear the stock variety and too many horror stories abound about questionable practices from "home made" crystal links ro diluted bottles of coolant. I used to by 'safe" things from them like fittings but since the new web site went up, I can't bear to shop there. I saw a lot about them being cheaper but i did a spreadsheet on a $2300 order and differences was $8 for items they both had and I had to go to two other sources to get the missing items
Other sources are run by decent folk but the stock is small.
I'm hoping it resurfaces in some form or another, run by some of the original crew .... otherwise WC will be a lot harder.
