I understand your concern about heat; when I built my workstation, I designed for lots of heat removal, but only to outside the case, as I intended to run it in a large, cool basement. Turned out to be too dirty (and especially dusty - sawdust is nasty - it's infinitely fine, and sticky to boot)) there, and wound up putting it in my small (~100 sq ft) bedroom; ran up the room temp to over eighty F in the winter with the room's heat vents off; couldn't wait 'till summer - had to WC it with a radiator a floor below... Have pictures of final result at:

BTW - those 20 C GPU temps are with the graphics cards OC'd as fast as the driver will crank them - used to run around 54-58C, with fans howling like banshees!
I'm fairly well awed by 7; they finally seem (which appears to be about every third product release) to have gotten pretty much everything right! I had done upgrades (not recommended, but I wanted to see if it worked) from the original TechNet release, to torrented 7058, to 7061, to 7100, where I found a few problems... I then thought to remove the upgrading problem excuse, and did fresh installs of the official Technet 7100 release candidate, both x86 & x64. Only two significant problems: one, I am certain is video driver related - I have a pair of 3850s, and both Catalyst 9.3 and 9.4 cause IE8 to crash whenever right clicking on a favorites entry; tried it at three different points in an install routine of perhaps forty programs - dead consistent; second, I think, is also ATI driver - often, when returning from using media center, I lose a monitor (four on system), but
not the one MC was on - which, of course, scrabbles up the placement of three dozen icons. Speaking of icons, that is probably the biggest bug I've seen that seems to be traceable to win7 itself; it appears to have an icon cache problem, and only with certain icons - occasionally, a few vanish after a reboot, and, likewise, once in a while, only with certain icons, an attempt to edit their text makes 'em go away, only to reappear after a reboot??? If I could identify the difference between the ones succeptible to either problem, I'd probably have the cure! BTW - same in 32 & 64... Both Enterra's IconKeeper, and the old, stand-by xp's layout.dll mostly fix it.
However, it's quick, adaptable, and, I do industrial systems, so I need to run a lot of really crappily written s'ware - the virtual xp machine is a godsend! The MC finally seems to work completely - with vista and the tv-pack, setup was always chancey, and sometimes would simply refuse to get it right, even manually... The built in iso burner has yet (probably thirty disks) to bobble a burn (and I'm distraught, as I just paid for Nero), and one other nice feature is right-click conversion of the new wtv files to dvr-ms. I'll tell ya, I had an MCSE back at win98, as I worked for a company that would pick up the cost of the tests so long as you passed 'em; when 2000 came out, we all took a pass, as it was obviously just a 'fill-in' in the revenue stream; same for ME (didn't even rate as a fill-in!); I might give recert a shot; this one's going to make MS some money, especially if they get the RTM soon enough to accomodate next year's xmas machine buyers... It's impressed me so much that I've finally bitten the bullet and undertaken to teach myself ceesharp and dotnet (which I also figure, seeing as how we're on rev3.5sp2, might be stable enough to bother with!)
MCE_Buddy works with 7 and vista, but, so far, is limited to 32 bit and a command line interface. I'll take another peek at Life Extender to see if they've caught up to wtv files; as I said, MCEB seems to have come to (I hope) a temporary development hiatus... Another spot I've found invaluable is:

I'm surprised you get no ClearQAM - I thought it was some kinda FCC thing that they
had to put QAM of local broadcast channels on; anyhow, not missing much - they mostly (here) are broadcast better on ATSC, and the few oddballs that aren't broadcast are wierd, local origination things that appear to have the res of an older ipod!
