So, I just grabbed an '06 for $80 CDN. Pretty stoked! It came with no BT and no WiFi option, a 250meg HD with 10.7.5 on it, and 4gb ram. Also, a GT7300. I've ordered 32gigs ram, which is due in next week. $100, hard to complain about that. When I can find a pair of x5365 or x5355 cheap enough, I'll swap those in. [Edit - just ordered a pair of the higher idle-wattage SL9YM x5355's for under $12 CDN] I've got the Pikified El Cap thing ready to go as soon as I have the ram in there, which will go on a new SSD - and here's where things get a bit confusing for me. 1. Will El Cap run on the 5150 chips? Or do I have to get the x53xx chips in there first? 2. Which PCIe card do I want (that allows a bootable volume) to get those newer Sata speeds 3. Which videocard will do a decent job of accelerating AE/Premiere Jobs and still work in a 1,1, or "1,2" since i've done that firmware update - I don't care about boot screen. I already have a GTX570, looking for something that will work faster for AE 3d things. 3. If the card is also supported by Blender, that'd be a plus. Thanks all - you were of immeasurable help when i was upgrading my 4,1 to a 12-core monster.
