The LAN sleeper... Walk into a LAN party and people say, "What are you going to do with that, put on a powerpoint presentation?" Little do they know...

Remove the existing 240w troublesome power supply and replace with 275w larger style. The screw pattern was the same, but the wires were not. I had to lengthen them to reach the MB power supply header. I didn't splice them together, I resoldered each bundle individually. The case fit was tight, I had to remove the some of the back and mod the bottom PS case floor locks.
The video cards were too close together to use the stock heatsink and fans. I found some old X1300 heatsinks and machined off the areas that interfered with installation.
Cooling is provided by a double 50mm fan from the old Pentium III days and I added a small 50mm fan to assist in keeping the cards cool. I added a potentiometer to both the front and CPU fans for better control of the case temps.
It does get a little loud when running a game or benchmark, but it is ultraportable and fun to keep up with rigs three to four times its size. It's about a tenth of the size of a Cooler Master Haf X case...but about the same weight...just kidding.
The good... Core I7 2600 Quad, 8 threads. Boots in 10 to 15 seconds. Runs most games in "High" settings. Very portable, at 14lbs...throw it in a backpack.
The bad... No overclock...thanks Dell! Must mod the cover to utilize the video card fan cooling. No Wifi. No sound card, but stock stereo for headphones.
The Ugly...Its a Dell 790!
Not a build for the average everyday person, but a good experience none the less.
Core I7...Need I say more.
Fastest low profile, single slot card in the US.
