You, sir, are correct. Hehe.
Rivets drilled out to remove the fixed drive bay.
Had to even out the surfaces somehow. Old wall trim was the perfect size.
Now, I had to make standoffs to keep the MB off of the wood and metal surfaces. Some old plastic hangers of some sort did the trick here. The holes were the perfect size for actual MB standoffs. I didn't want to risk just screwing the MB standoffs into the wood (as they may have ripped out overtime), so that's the reason for all the jury rigging. It took about an hour to align everything. It took a lot of guess work.
So, then, so far in about 5 hours time I completely removed the drive bay and fitted the MB. Now, any ATX MB will fit in this case.
Next up: Cut the steel out for the I/O panel. Hopefully I can get the MB's I/O panel to fit. If not, I'll just leave it open, no biggie. Then, I'll need to figure out how I'm going to fit in the CD/DVD drive. I'm thinking I'll enlarge the hole where the old PSU used to be fitted (the very small rectangular hole mid-way up the back of the case). I'll have to figure out some kind of bracketry. Also, where the old expansion slots were I'll be cutting them out and placing an 80mm intake fan there--probably put one where the old exhaust hole was as well. Oh, and btw, the hard drive on these old Gateway cases actually mounts at the top of the case, so that'll probably still fit there. I'll probably end up mounting the PSU outside of the drive bays. When it's all fabricated, it'll get a coat of fresh black paint and hopefully some kind of design.
