Pros: Zalman ZM-RHS1 thermal pads = 107% stable overclock. I then remove those pads and use this stuff, 125% stable overclock. This stuff is for serious work and produces serious results.

Cons: Um, permanent, you don't get to change your mind, but it's epoxy, so it's not really a con, thought I'd throw it in so you think before adhering.

Overall Review: Haven't had a problem with it conducting electricity yet, but I'm careful and detailed when I do that stuff. If you are considering purchasing memory chip cooling solutions, strongly recommend.

Pros: Very fast large capacity drive, ideal if you want something to store lots of data that needs lots of bandwidth, say movie editing or high end photography, which is what I do.

Cons: Um, none, *mind draws blank when trying to pair a con with this thing* Oh, well 3 year warranty vs a Seagate 5 year, but you know what, that's not a con to me, having been in Computer Business Sales previously, you get an extended service plan or you don't, if you don't, standard warranty service is slow, and usually painful, but of course free, 5 or 3 year painful coverage, eh, not much to hoot about.

Overall Review: Powermac G5 2.3 Dual, it rocks. Good pair, I'm getting 96.73mb/sec read and 94.01mb/sec write throughput on this thing which is outgunning my Raptor X in purely sequential data read write performance (not to be mistaken with random read write). My Raptor X still has wicked response time and is still faster for Apps and OS loading and server processes (and my OS and Apps are on my Raptor hence) but I'm only getting 64.15mb/sec read and 61mb/sec write on the Raptor X. This thing holds it's own, rock on Western Digital.

Pros: Lightweight, low and high clearance sinks, excellent design (disperses heat very efficiently, material isn't everything, although it does matter) Thermal pads stick very well, they also aren't too bad to take off if you want to use thermal epoxy instead. Backside heat sinks are genius.

Cons: Would like to see more sinks in a package for newer cards as 8 full sizes is what you're looking for with say a X19xx or 7xxx, but you can always buy two, and you get backside heat sinks, which is awesome.

Overall Review: Thermal pads in general, stink for OC. Why? Used them with the pads they came with, OC at 107% of stock stable, with Artic Silver ASTA-7G, successful overclock of 125% of stock stable. Yeah, that much. Copper is better, also more expensive and heavier, but as I said, design on these rock, get these, or get Thermaltakes CL-C0025 if you need low clearance, or get Swifttech MC14 if you have the clearance and want the best of the best. These things though, are totally awesome. As always clean your surfaces before placing and results vary, but these things I recommend highly.

Pros: System sees roughly 8% overall performance gain on memory access intensive apps (Final Cut Pro, Handbrake, ripping cds) and interface is far more responsive. Cheap, effective, and if you buy two instead of the dual channel kit, they run in dual channel mode, you don't have to buy the kit, and dual channel kit is always out of stock anyways. Heat spreaders are cool.

Cons: Um, none, no seriously. If I were to find one, uhhh, none, totally awesome, it's the best ram you can throw in a G5 with ddr2.

Overall Review: System profiler will detect it wrong, but after extensive research, yes, it will run at 533 with a latency of 3, despite what others have reported, and benchmarks confirm these findings. This is the best you can buy for a late 2005 powermac g5, period. System profiler sees it wrong cause it reads only the first line of code, which isn't the same on non-apple certified chips.

Pros: It's copper, which means it is 3 times more conductive of heat, but only radiates it 50%practically, still, not bad. Low profile, so it works with my Zalman 9000 no prob.

Cons: I clean my stuff really good, and follow instructions to the tee, been doing OC'ing for ages, but still the sticky tape, dude, it fell off with one bump while inserting my card back in my computer. Get silver adhesive, but fair warning, silver adhesive, is permanent, so not for the timid, but I recommend silver based adhesive and silver based paste for OC anyways, it goes a long ways to helping it do it's job and get more power out of your card by cooling it the best you can.

Overall Review: Cheap, copper, and low profile. Fin design could use improvement, but it's still better than aluminum by far.

Pros: Highly addictive, serious gametime (good value), lots of replayability.

Cons: Highly addictive, serious gametime (no life), AI is stupid with naval warfare, I murder it, everytime. No editor (there is one for PC and there is one for CivIII for Mac, but not the Complete Mac version)

Overall Review: Runs great on everything from 500ghz g3 and up, but yeah, the more power the better, especially when you hit the modern age and you're running a huge map. Good land grab strategy game. If you've played any of Sid Meier's games, say Alpha Centauri for example, this is a must have.
