So you say that your current limitation is currently disk (and possibly
RAM), but you are spending $1,100 mostly on CPU (and RAM). Personally,
I'd take that money and buy a hardware RAID controller and as many disks
(in the $/GB sweet spot) as I could to use with my current set-up.
Assuming your current computer does not have a PCI-Express slot...
4 Port 3Ware SATA Raid card* - $310
http://www.newegg.com/Product/Product.aspx?Item=N82E16816116052
If you DO have a PCI-Express slot...
4 Port 3Ware SATA Raid card - $275
http://www.newegg.com/Product/Product.aspx?Item=N82E16816116076
In either case...
1.5 TB SATA Drives - $145 each ( $725 for 5, so you have a spare)
http://www.newegg.com/Product/Product.aspx?Item=N82E16822148531
That leaves at least $65 for shipping and molex to SATA power adapters.
Run the four drives in RAID 5 for maximum space, or RAID 10 for
(possibly) better performance.

* PCI-X is backwards compatible with PCI, so this card will work in a
PCI slot.
