The kit came with a thick plastic sticker that I was'nt totally sure what to do with but it made sense to use it to cover the solder points on the lower ribbon cable as the metal shield of the PSTwo will come very close to these solder points and could possibly short. Below is what that looked like.
At this point I was then done with the ribbon cable install and could now turn off my soldering iron. Next comes the reassembly of the console.
Reassembly
After I reattached the PSTwo?s metal shields I then installed the HD-Combos large ground connection. This ground is a bundle of wires with an eyelet on one end and the plastic connector on the other. The eyelet goes under one of the lasers screws and when tightened down stays in place nicely. I then sat the motherboard into the HD-Combo?s lower plastic case housing which fit very nicely. I then plugged in the large ground plug and the ribbon cables into the HD-Combo. Below is what all this looked like.
I then set the original PSTwo?s top case housing in place and screws the case together.After that I screwed the removable plastic door that?s on the bottom of the HD-Combo to my HDD with the provided screws.
After this I attached the HD-Combo?s IDE cable and power plug to the HDD.
I then inserted the HDD and the removable door snapped right into place with its quick release lock holding it in place.
I then plugged everything into the PStwo.
I flipped on the power switch on the back and the HDD spun up and the LED on the front of the HD-Combo lit up bright blue.
I turned on the PSTwo and Toxic OS detected my HDD just fine. I proceeded by installing a few games with Toxic OS right on the HD-Combo. I then went to play them and through Toxic OS and they both played great! The LED also shows activity. When there is activity the LED will turn a bright pink. Here is a short Divx clip of that.

Overview
Overall this is a very well put together modification and well thought out. Everything is now contained in one package and the HDD is now incased in the unit and very sturdy. The HD-Combo?s case is very high quality and fits very well. The added switch on the back of the HD-Combo makes turning off the HDD very easy and the HDD activity LED is a very nice feature. The two internal fans in the HD-Combo is also a wonderful feature to help keep the HDD cool. The air passages and grilles for the fans on the front and back were also well thought out. The quick release door on the bottom is also very easy to use if you ever need to get at the HDD for reasons such as installing your games with Winhiip on your PC if you like. The ?Y? adaptor clears up a little clutter in that now you only need one AC cable for two power supplies. For those that are concerned with the size of the slim now being bigger I have to say that they did a very good job and still maintaining a smaller profile for this mod.
Suggestions
This is where I would like to add my personal thought on what might take this product one step higher. Don't get me wrong this product is great but everything has room for improvement. What I would have liked to see would have been one power supply that would handle both the required voltages (actually three voltages, 2 for just the HDD). One power supply that would have a 8.5V output for the PSTwo its self and the other would be the 12V/5V for the HD-Combo. Now this could be done externally like it currently is or what would be very cool would be an internal power supply that did this that you could just run the AC cord to the HD-Combo. This however would eat up room in the HD-Combo as there is no room as it is and in turn needing a bigger case and a more complex PSU which in turn would jack the price up more. Another feature that would be kind of a luxury and my not be used by many but would be nice to see would be if the HD-Combo had its own USB port. His could be used to install games directly to your HDD over USB on our PC. Maybe the switch on the back could be a 3 position switch with one being HDD off, one being HDD on and the other being USB mode. When in USB mode a USB to IDE adaptor would be activated and turn off the power to the PSTwo all together. In this mode you could then install your back-ups to the HDD with a USB cable with your PC and Winhiip. Now wouldn?t that be cool! This would of course also drive the price of this product up more. Maybe we could have a lite and pro version

Anyway these are just suggestions, take them as you will.
