Lucky for me, the processor was the step E1, but it didn't matter anyway; the motherboard's firmware was a few versions past the minimum needed for either version of the chip -- 1.50 if I remember correctly.
The heat sink came with a small amount of thermal compound on it; but I went ahead and bought a pack of generic stuff from a nearby computer store (Schroeder Software in Dodge City, if you're interested). If I was planning on overclocking at all, I probably would have spent the extra money for Arctic Silver, but since I was trying to ensure coverage rather than maximize efficiency, what I got will work.
The salvaged hard drive did indeed work as intended, even though I hit one hiccup with the previous install of Windows XP on the drive before I figured out that I had to use the drive menu interrupt to boot from USB.
The power supply appears to be adequate for my needs, at least for the time being. I'd be nervous if I had a discrete video card, or multiple drives. But as it is, a single hard drive, the motherboard, and a USB memory card reader don't seem to tax it beyond reason.
The biggest issue I've actually run into was my own stupidity. I never thought about the MTX suffix on the salvage machine's motherboard indicating that it was a MicroATX board. Since the Z77 Pro3 is a full ATX model, I had to go out to the shed and dig (and clean) out a larger case. Unfortunately, this case does not have a ventilation solution. Or rather, there is a single fan mount in the front, and the rest is passive cooling. So I declined to replace the steel outer shell, and have it open to the air. I'll need to keep an eye on the temps until I get a new case.
As for the operating system, I'm currently running Ubuntu 12.10, both because it's free and because the installation media fit on a 64MB flash drive I had sitting around. I don't mind Unity, especially since the effects don't drag like they did on my Celeron M laptop. Over the last couple of hours, I have made some changes to the standard Ubuntu install:
- The Fonts task. During installation (where you choose which desktop version and tasks you want), you can add a lot of fonts. If I'm not mistaken, that's the actual name of the task: "a lot of fonts."
- google-chrome-stable: I don't mind Firefox, but I've been using Chrome for a while, and I like it more. So I grabbed the deb file from http://chrome.google.com and installed it.
- steam-latest: Head over to http://store.steampowered.com and grab the free Steam client from the Linux page. The client is in beta, but there's a good 40+ games there that run natively in Linux, including Team Fortress 2, FTL: Faster than Light, and Amnesia: The Dark Descent.
- vlc, audacity: It shouldn't be a surprise that I enjoy music. So I always grab the VLC media player and the sound-editing program Audacity.
- Privacy Settings: Yeah, I don't like that "search our internet partners from the dash" feature. It got turned off real quick, along with a couple of other options.
- Wine. Yeah, I know. Using Wine seems like a cop-out, but there are a couple of games I really like playing, and don't want to give up just because I can't afford a copy of Windows right now.
