I have decided to take this guy up on his offer.
However, I'm still in contact with three other sellers. So if anyone is looking for an Apollo/Blizzard, PM me.
On another note: I've just received an offer for a Mikronic Z3i for 150 euros + shipping.
Might this be a worthwhile future update?
EDIT: Ok. It cost me quite a lot of money, but I'm 80% there.
After waiting 12 years for my Amiga (about the same amount of time people in the USSR waited for their cars. Lol), it took me less than a month and approximately 700 euros to source nearly all the components I ever wanted to have.
Bought 2*128MB 50ns Superslim EDO (the last the Ebay seller had in stock) today (they cost me about the same as my 16GB high-end DDR3. Ouch), already sourced a Z3i for a possible future upgrade to Cyberstorm(PPC) or UltraPPC (if that ever comes out and supports Amiga 1200 busboards) and am about to drop some money on Amiga OS 3.9.
Am I one lucky son of a bitch or is it money that plays a huge part here? Personally, I'd have imagined it to cost about two to three times as much as it ended up costing me. Going by what someone on here said, the Micronik alone should've cost me quite a dime.
The only thing that is now left finding out is whether I can install a Micronik Z3i and a Mediator at the same time or not.
This and I'll need some documents on how to successfully mod an ATX midi/big tower, since I really don't want to spend money on something as generic as the Amiga specific towers.
