Wow, so glad to see this thread, Think I'll call the shrink and cancel all my appointments! I'm not crazy afterall!
7 working ThinkPads, 2 in daily use:
755CV - i486DX - Bought for $50 off CL, MINT. Will keep as museum piece
760XL - Pentium 166 - Bought for $25 off CL, Absolutely MINT with battery that still holds a good charge. This is my newest, and we are still bonding at the moment.

She's a
beautiful lady. Will keep as museum piece.
570 - PII 366MHz - Given to me by the porter of my building before I moved from New York. Screen flickered, and USB port was broken. Have replaced the MoBo and fixed the flicker. (Porter laughed when I told him I wanted his trash, was really *****Expletives removed by Moderator***** when he saw it all cleaned up and working again)
570E - PIII 500MHz - Bought from
Eric Giles, it came with all original box, docs, etc. Beautiful machine. I'm waiting to put a SSD in this one. Have added wireless with an external SMC antenna attached to the back via the modem cutout.
T21 - PIII 700MHz - Purchased off eBay, but got burned. Screen had undocumented red tint, but has since been replaced. Not really sure what to do with this one.
X31 - PM1.4 - Purchased as refurb from IBM. My take out machine, though she hardly ever leaves the house.
T43 - PM1.7 - Purchased as a refurb from IBM as well. This is the machine I use for internet when I am in couch potato mode.
I also have 3 desktops that get pretty much daily use, 2 others that lie in wait for use. I like to buy IBM chassis off eBay to rebuild.
Desktops:
Intellistation E Pro (the only stock desktop I have) - PIII 933MHz with VIA chipset. Keep to show that PIIIs are actually decent machines when not used with an Intel chipset.
NetVista legacy free SFF - rebuilt with MSI K7N MoBo, a new power supply, and Athlon XP2500 and 36GB Raptor. This machine flys and has served me well for the past three years as my main internet machine.
IBM eSeries 235 chassis with nice perforated metal front. (Introduced WAAAY before Jobs stole the look for the Mac) Rebuilt with MSI Socket 939 Athlon X2 4400, 4X250MB sata drives, two of which are raided. This is my work horse, file storage, video, graphic design, heavy photoshop use.
NetVista Minitower - Rebuilt with Intel 865 MoBo, P4 2.8 Prescott. This is my test machine which I use for uTorrent and Norton. (I run Norton on this machine only. I'll pull hard drives out of all the others to scan them if I need to.) Still looking for pinout for the front panel audio jacks so I can hook them up to the MoBo.
Cheap aluminum thing purchased from Tiger Outlet (It fits where it needs to go, still looking for a good IBM replacement case though) - Fitted with an ASUS MoBo, socket 939 Athlon 3700. OS is on 36GB Raptor drive, 250GB WD serves for 215GB of iTunes storage and video player.
And all this crammed into a one bedroom apartment! Visitors mistakenly think they are in Best Buy upon initial entry.
What's the obsession? I'm an IBM brat whos' father sold mainframes for 32 years, but who also would never buy a PC for the house. ("I'm not spending that kind of money, only to have it worth nothing in a year." Was a stock response to my pleas in the 80s) I started using the Mac after graduating from design school. (oh, wait, I have ANOTHER desktop a 533MHz G4 Apple Digital Audio, but it has not been turned on in 3 or 4 years)
Used the Mac for 14 years until Jobs returned to the mother ship and threw out all those things that made a Mac a Mac. OSX marks the spot where the Mac died IMO. I purchased my first PC, an IBM 300PL 6892-N4U 5 years ago, and haven't looked back since. (since parted out, but you never forget your first time

)
My father, brother and three of my best friends work or have worked for IBM at one point or another over the past 20 years, resulting in raging fights over the merits of Mac vs IBM. One Thanksgiving dinner stands out in particular, although no food was thrown. All are very pleased I have finally seen the light.
