This is the most recent computer I built for myself, if I recall correctly, right after I graduated college, which would have put it early 2009.

Since I've been trying to do video editing for the youtubes I've really come to notice just how slow it is, so I decided on an upgrade. I ran a preliminary benchmark just so I could see what (if any) improvement there would be. Unfortunately even the "newest" processors the board would support are around 7-8 years old now. Parts I used for the update include an AMD Phenom ii X6 1090T processor, 4x 2gb Corsair Dominator DDR2 6400 (apparently this mobo will only support 2 sticks of the 1066mhz ram, so I went with 4 sticks of 800 mhz that's supposed to be a tier above the XMS2 line), and a Corsair H60 liquid cooler.
The liquid cooler was a PITA, because while I couldn't find it documented anywhere, I apparently needed to adjust bios settings to ignore the CPU fan speed before installing it, as I couldn't even access bios the first couple of times I tried to boot. Having a very slim case, I also had to make some modifications in order to be able to mount the radiator, which now sits on the outside of the case. I still haven't gotten the case fully reassembled as I'm going to have to make some more modifications due to the real estate used by the new ram's heatsink. It seems to have some interference with the optical drive/hard drive cage, but nothing a little clearancing with a grinder won't solve. Anyway, here's where I am now, at least until I can get home and reassemble:

...and the benchmark test once everything was in with updated drivers, etc. It's also worth noting that under the test stress, CPU temps dropped from ~43C to ~23C going from the stock heatsink/fan to the liquid cooler, so there may be a bit of room to OC the processor without having to worry about excessive heat.

Given the jump in the overall score, I'm really hoping that this will let me process videos a little quicker. So far, not a bad upgrade for $150.
