you did a really nice job. as far as the paint job goes, i think you did good on it, but i also think you got the wrong paint. i personally would have looked for a flat black or an outdoor paint of sorts, possibly applying a case sticker.
as far as the system itself though, i'm a bit confused...
-Crucial PC2700 RAM (2x256) 333FSB.
-AMD XP2500 - Overclocked to 2.14Ghz
-NVIDIA eVGA 6800GT 256MB RAM DDR3. @ 380 x 1.10Ghz
not sure what that ram is capable of, but i'm sure if you'd relax the timings a little bit it could probably get a full 200x11 @ 2.2ghz xp3200 overclock. mine hits it really easily. can go over, but things go to hell from there. i actually sold my processor and am waiting to get my mobile xp2600 with a thermalright sp-97 so i can overclock to 250x10 @ 2.5ghz
the video card, are you sure you can't get it to run a bit faster than that stable? most 6800gt's will get you 400/1150 atleast... most of them even higher than that. my friend's 6800gt gets 423/1170, a nice improvment over ultra speeds o_0.
it will run hot of course, but they run stable hot, so it shouldn't be too much of a problem. if you're having the problem where it hangs for a moment then resumes operation you may need to try disabling fastwrites (though it's reccomended to have them on). if you get the problem where it's running fine then stops for a good 10 seconds, then continues fine... you're having thermal throttling problems. in that case, you should find a way to increase the cooling, maybe an upgraded vga cooler by zalman or something, they can be had for pretty cheap.
not sure what you value as far as overclocking, definitely an excellent system you've got there. i know personally i'd like to squeeze more mhz out of it if i were you, but then again you're talking to the guy who just fried a memory channel because of trying to overclock too high setting the vdimm voltage to 3.3v (2.6 default), lol.
