Hey everyone, this will be my first Hackintosh build so you'll have to forgive me for my noobish-ness. I recently rescued an old PowerMac from a local ad on Craigslist. It's a relatively good condition B&W that I've decided to turn into a Lime Green & White PowerMac G3. I haven't gotten the budget (my girlfriend is expensive ) to order in all my parts just yet, but I have the following shopping list: CPU: Intel Core i5 3570K (already purchased) Motherboard: Gigabyte GA-Q77M-D2H PSU: ThermalTake 600W RAM: 8GB. I don't really care about the "high-performance" RAM SSD: 120GB Samsung 840 HDD: 500GB Whatever's cheapest brand. GPU: TBD. I don't game and I have a Mac Mini that works fine for watching movies on a slower Core i5. OS: Mountain Lion Now, seeing as this is my first Hackintosh and my first custom build in general, I have a few questions. I've already read fairly extensively so I'm asking to those in the audience that have experience regarding the following topics: PSU: Does having the standard format PSU cause any real issues in regards to heat? The stock PSU is obviously a one-off setup and isn't compatible with newer mobo's. Case Fans/Heat: If I only primarily use the computer for homework (I'm a broke-ass college student), and general internet browsing, should I really even concern myself with extensive cooling? The heaviest load I will ever be running will be Safari, Mail, iTunes, and Pages at once. GPUs: For what I described above, is there really any benefit whatsoever trying to cram a GPU into an already-tight case on a small mATX board? I hope to have the motherboard, RAM, and HDD here within the next few weeks to get this project started. For now though, I'll make a trip to the local Lowe's and grab some paint prep to get this started. Attached below is a paint scheme from an iMac G3 that I'd like to come close to, perhaps a few lighter shades of green.
