Looks like he de-soldered two RAM slots as well. Not ideal
Not exactly true. MDD can support 1 Gig DDR memory sticks. With 2 you achieve Maximmum.
It is a pain in the ass to pull them off but at the Japamac/bdaqua/MacTron proof of concept level, the limit is nowhere.
MDDs are flexible. If you want room for the heatsink you take 2 there. If you want room for the AGP with modern double height fan, you can choose those other...
Great if you are Going SATA... but looses Ulta-DMA PATA/IDE 100 controller, no room for Hard drive there, Also Extra Fan on Back of case probably adds Noise also
Yes, you loose room. But there out are dozens of 775/1156 heatsinks smallers than stock heatsink... The shit is to adapt them. Most mods made by Japamac/bdaqua/MacTron involves tools (Dremmel/saws/etc) that most of us don't have.
Even if you loose that place, you can still wire the IDE 100 controller to any other place, like over the CD bays or instead of the IDE 66 ones or even outside.
For sure 3 fans at full power sound louder than the original one.I would had changed that fan inside for a thin one between the plastic from outside and the metal cage as I ve seen elsewhere. Or cut the 2 bay to make it 1 bay.
