Granted you want to save money, I get that.
But by the time the 3000 is released in July, you should have saved up quite a bit more money, since it is 4 months away until the rumoured release.
DRAM is dying a death, finally and getting down to normal prices, the same can be said for SSDs as well.
So if you spent $1000 today, that same system components would be probably $750 in 4 months, if not less.
