Sega "Neptune"

So, a long while ago I came across a mod to install a 32x inside of a Sega:

It's a fantastic idea and I certainly believe this would fit into my small collection of showcase modded consoles.

I've never owned a 32x and I would like to propose a question; Is there anything I should be aware of that would make this "Sega Neptune" an undesirable choice as a day to day console? I'm worried about committing, only to find out I'll be restricted in some fashion with the 32x permanently attached.

Here's my list of expectations for this thing:
- RGB output
- Sounds pristine (via Crystal Clear Audio Mod)
- Can run all MegaDrive/Genesis/32x/Master System games
- Case's exterior is physically identical in appearance to a model 2 Genesis (I'll be using my Everdrive MD to play 32x games, to avoid modifying the cartridge slot)
- Would like to potentially have a SegaCD attached.

I'm anticipating having to potentially upgrade the power supply, being as that the stock Genesis AC adapter will be powering the console, 32x and my Everdrive MD.

So, any thoughts on any restrictions I may face?

Since my post, I've discovered that SMS games will not work in a Genesis while a 32x is attached. Slightly disappointing, but probably not enough to deter me. Anything else?

That's about all. For sms awesomeness I built the following:

really though out of all the 32x stuff - blackthorne and knuckles chaotics are worth playing. I cant think of others - mabeye i missed some.

but personally, id rather have master system compatibility.

That's a fairly compelling argument. Maybe I'll put it on the back burner until I get an SMS2 that I'm happy with going.

For my Sega CD / Genesis I just got a 10 volt AC adapter with 3 amps instead of whatever the stock was, then soldered it to two different cables with two plugs of the appropriate polarity for the Sega CD unit and the Genesis unit. That allowed me to use a single AC adapter for the entire console, without having to modify the consoles themselves. Plugs were free (came off of old printer AC adapters).

I'd guess you could do the same thing for the 32x.

Sounds like it would work. I wonder how many amps you'd need.
