Busy with PC Maintenance

Getting a new PC ready for the living room. It's the one my wife uses, and the Windows XP Media Center installation on the big Dell Dimension E510 she bought several years ago has gotten rather "constipated" with sludge, as Windows has a tendency to do. It's had so much stuff installed and then uninstalled, that the Windows Registry is gunked up, and all the utilities I have can't get it clean again. Sad, but true, the only way to get it running smoothly again will be to do a complete wipe of the hard disk, and reinstall Windoze. Such is life in the Windoze Universe!
BUT...my son the budding Photojournalist has decided to go 100% Apple Mac, as all the specialized software he uses for photo editing, video editing, and publication runs much better on the Mac, and since he's been doing this since high-school on Macs, it makes perfect sense for him to go this route.
Two years ago, I built him a Bleeding Edge PC, that was right at, or slightly beyond, State Of The Art, and ran rings around any "Store Bought" PC system, even the high-end ones like Alienware and VoodooPC build. He pulled the hard drives out of it as they have all his work product, and dropped it off here last night.
I pulled it apart, cleaned all the dust out of it, pulled the heatsink/fan off the processor and cleaned the original thermal grease off, and put some Arctic Silver 5 on it. I also neatened up the wiring, and installed a new 300GB Western Digital 10,000 RPM "Velociraptor" hard disk.
I put Windows 7 Professional on it this morning, installed the latest versions of the drivers for the motherboard and video card, and installed all the programs my wife uses a lot, like Microsoft Office, Adobe Acrobat, and a few others. I'm just finishing up getting the drivers for our printer and other devices, and so far so good. It's scoring a resounding 7.5 on the Windows Experience Index, quite amazing for a two-year old PC, but then I put the best available parts in it when I built it. And with the type of computing we'll be doing with this PC, it will run as cool as the proverbial cucumber. Her Dell blows HOT air out of the vents when we start cranking it up, so this one should use less power, and save a few bucks on the electric bill.
Oh, well....time to get back to "work" here!
