I really don't know much about it. I bought it several years ago and I forgot about it. I made a quick video to show what it has. Can anyone tell me any details or what its worth?

If it has a HDMI port its a Zephyr, but if it does not then its a Xenon

It doesn't have a HDMI. So is $100 a proper estimate?

Some people say a "reflowed" Xenon JTAG is the best to have. If the OP were to reflow and get rid of M$'s cheap thermal paste, it could be a good machine.

no a reflow is a temporary fix, and a reball can be a permanent fix

i know a reball is where you completely take the GPU/CPU off and replace the solder points but whats a reflow? is it just heating it up so the solder points melt then return to their proper place? :/

A reflow basically means to remelt the solder under the chips

Code:
A reflow basically means to remelt the solder under the chips. Under most of the chips on the xbox are a grid of solder points called the ball grid array (bga). With bga chips you simply can not use a soldering iron. Bga reflow machines use either hot air or infrared to heat the solder to above 450F.
 
I own a hot air bga solder rework/reflow machine and here's the process i use for reflowing xbox's.
 
First i clean the processor so there's no thermal compound left, then i apply no clean flux under the chip that i'm reflowing. I pick the proper sized nozzle to fit the chip. I then mount the circuitboard to the preheating table and set my preheat temps. I usually set the preheater to 240C which is about 460F. I let the board warm up for about 5-10 minutes till it's roughly above 220F.
 
I then turn on my hot air and set my temps to 90C which is about 200F. I wait a minute or 2 then up my temps to 190C which is about 370F. I wait a few minutes then slowly raise the temps to 300C (570F). I hold 300C for about a minute to a minute and a half (depending on the chipset) then i slowly back my temps down to 190C,90C then off. I let the board cool for about 15 minutes and it should have been a successful reflow.
 
I've reflowed ps3's, xbox 360's, a few hp and compaq laptop motherboards and even reflowed a bga chip on a router. With a successful reflow you can reinstall the xclamps but i usually replace them when i'm done.
 
Here's a picture of my reflow machine

Most people can't afford a machine so they use a heatgun. With a heatgun you're more guessing what your temperatures are than holding a certain temperature for a certain period of time. People get lucky with a heatgun though it's not a real reflow.
