Hey all: So every year since 2003 I go to QuakeCon and compete in the case mod competition. Typically, every year I have placed top 5 with the past three years 2-2-3, respectively. Its always a lot of fun, and I usually win enough cash to break even on the computer. Ever since I dumped the PC laptop for a MacBook about 5 years ago now, I haven't really used the PC for much other than gaming, and due to law school, I don't have time for much of that anymore. This upcoming year I'm wanting to do a case mod with a MacPro. I have absolutely no interest in doing a hackintosh as the back end of the Pros tend to get butchered beyond repair. So, here is my thought, I've got about $1500, $1750 tops to spend on the MacPro its-self with another $1000 set aside for the mod, and another ~$750 set aside for more ram, graphics card, and SSD. I don't need some 12 core monster, but getting a dual 2.66 MP 1,1 doesn't seem too appealing either. My big hangup is I down want to feel a slow down from what I currently have - Current specs . . . . i7 920 @ 4.1Ghz HD 4890 12 Gb DDR3 2x WD Raptor X's in Raid 0. So I guess all that being said, what kinda MacPro could I get for $1500 - $1750 within the next 2-3 weeks? Thanks! Edit --> Worth it to spend the extra $250 to do the single Nehalem refurb. off the Apple store?
