What on earth laptop do you have with all that for $1000? Or maybe you mean $1000 in upgrades, but still... what laptop will take 64GB of ram and 4 disks?!
A ThinkPad P-series workstation takes four disk drives: two SSDs, one HD, and one DVD. It has four RAM slots so you can have 64GB. Low-end CPU is an Intel Core i7-6820HQ but you can upgrade to a Xeon.
The Dell Precision M6800 (no longer available) supported a 4 drive configuration if one was a Mini Card plugged into a slot on the motherboard, It had three 2.5in drive bays. You could have a look at the current Dell models, or an HP Z Book.
It's a highly configurable, professional machine.
