hello, i found a PSU on newegg, it's a 450 watt for only $19.99, plus a $10 off rebate so it's only $10 after everything. it's bronze rated plus, and it will work with the parts I'm considering using, i don't have a lot of money right now, so i can't buy all the parts to build the entire rig yet. So i was wondering if you guys think it'd be a good idea to buy the part while it's on sale, even though i can't buy everything right now.
