New build worth it?

Hey guys, i have hit a bit of a dilemma and I need some help. I have the parts to a new gaming rig all in a cart (Newegg and tigerdirect) and ready to order. Here's my problem. It's pretty spendy ($2500). I have the money saved up for it, and this computer will be for gaming/etc. @ college. My parents think I'm crazy for upgrading from my "current" PC, which i built for $700 2 years ago. The processor itself isn't terrible for gaming (Phenom II X4 955 BE). You can see all the parts in my Sig. However, it's not at all worth dumping money into upgrading this one. I'd have to strip out the mobo (no SLI support) the PSU (too small), the case (only midtower, too small), and the vid card (getting 2 new ones). Why go through all that work when it's essentially building a new one anyways. Plus, if i build a new one, I could leave this one at home and use it to run Minecraft and other game servers through RDP.

However, as pumped as i've been for my grad checks to go through (which they now have, so I do currently have the money to order the parts), the last day or so i've been really thinking, and this is where any of you with recent college experience could have some amazing advice for me. As much as I know this computer will kick-ass and chew bubblegum (but we're all out of bubblegum), the fact of the matter is that it will leave me high and dry in terms of money. I'll still be working this summer (6 more 1-week paychecks) that I could bring the money i get from them to college. But will that be enough? Note, this isn't about paying for actual books or anything, that's all gonna have to be student loans. My parents seem to think i'm gonna need $2000-$3000 for "fun money" and for chipping in gas money to rideshare home every few weekends (only 1.5 hours away). That seems a bit ridiculous to me, especially since i'll have a part time job up there (already got the hook-up). So the way that I see it is this computer is pretty much an investment. It'll be putting money down on something physically tangible that I can use for the next 5 years. I don't smoke/drink or party or anything like that, but I would hate to slowly deplete my money by going shopping for stuff i'll probably never touch. So, all-in-all, do you guys think that for college and for $2500, is the following build worth the upgrade over my old one in my sig?

TL;DR Is the build below worth $2500 to bring to college over the build in my sig?

Thanks again guys!

The most obvious part would be the Level 10 case. What other parts would you advise. I know the SLI may seem like a part to cut out, but personal preference makes me want to keep it, as I know I'll buy it eventually. The other spot is the mobo. That's one spot I could shed $150-$200.
