I've been using my G5 as my main machine for a few months now. My main PC (An HP Pavilion 500-070) died, well the motherboard fried. I was planning on replacing the motherboard and using the G5 for a short in between time. But I got really used to the G5 and Mac OS X as a hole. I've used OS X somewhat in elementary and middle school, I also have a Macbook. So OS X wasn't brand new to me, but I never used it as a main OS. So, I figured instead of fixing the HP I'd like to just go and save a lot of money for a nice 2012 Mac Pro. I'd like to save at least $1,200. Being 17 years old, thats going to take some time. So I'll be using my PowerMac G5 for my main machine for possibly the next year and a half. Video editing, YouTube, Web browsing, spotify. Everything. So I'd like it to run as fast as possible. But speed isn't the only issue. The fans are very loud. Not even a small buzzing noise, I mean I feel like I'm sitting right behind a jet engine. So I'm wanting to go water cooling. I've never done this before. Obviously some case moding would be needed. But I'm wondering if anyone can give me some tips or tell me if it's even possible or the speed improvements would be worth it. Current Specs Dual 1.8GHz G5 1 TB WD Blue HDD 1GB RAM (Original Apple RAM) 64MB NVIDIA GeForce 5200 Mac OS X 10.5.8 Upgrades I plan on -Same CPU- (I don't think upping it to a dual 2.0GHz will do much) 1TB WD Blue HDD + PNY 240GB SSD (Boot drive) 4GB RAM Some sort of 256MB card, haven't decided yet Dual Boot 10.5.8 and Ubuntu Mate Would the spec upgrade alone be enough? Or would water cooling truly benefit this Mac? Oh, I also plan on getting an Asus 27’ 1080p MX279H monitor but whatever card I choose should power it just fine.
