The decision has been made: i'm going to sell off part of my collection. The M4700 will be the first one to go, followed by the M60.
A hard decision, but space is increasingly becoming a issue, and I don't even use most of my 15" Precisions anyways. I will rebuild the M6800 and keep that one since it's a Covet and I already bought the parts for it in the USA.
The idea is to sell off the M4600, M4700, maybe the M6700 Covet as it's lid is ****ed and I can't find a new one anywhere, the M2400, M4300 and some of the Pentium era Precisions too, like the M60. Machines that I will likely never sell are the M6400 and M6500, Dell Internal Use Only M6300, the M40/M50 or the M70.
