First PC I remember was that Amstrad that had a fan in the screen to "cool" the cpu (despite being in the box underneath)
No really fond memories of that so my first PC was a really simple HP 386 with a meg of ram and a 14" via monitor, dad "borrowed" it from work in 93 so I could learn DOS before writing was important (and play Raptor call of the shadows and Hocus Pocus when shareware was a brilliant thing). PC's back then were way cooler, we had a few odd Pentium and pentium pro boxes from his work round the house followed by a range of later 90's unix work stations we'd put windows on so I could game when they weren't "testing". Shame they all got sent back to the USA when his company ditched it's UK wing.
My first build in 05 was:
Athlon 3000+ (replaced with the opteron up 148 that just pulled 3ghz)
Terrible Foxconn board (replaced with an Asus SLI board that overclocked)
512mg ram
Originally it was a 6600gt, nice and cheap card but replaced ATI X800 gto2 (the OCUK special you could flash the bios for to make it an xt with 16 pipe lines) -
80gig hdd
Looking the gto2 was the coolest addon my mate bought one of as well (I flashed it for him), even if we discovered how bad the Linux ATI drivers were, spent too much time switching cards just to run civ4 in gentoo linux...
Half of this is not retro enough so the best memories are going to my neighbours house and playing Amiga 500 games on that instead! He had all the best PC games when we were kids
