I have an XLATX motherboard from Gigabyte, their 890FXA-UD7

The problem with deviating from the standard is it limits the case choices, esp. with the extended ATX factor. I have not found myself hampered at all by the standard ATX. I would not go for a smaller board, even on a HTPC, because a larger board gives more room on the board for cooling options.

i have standard atx but you really forgot the xl-atx its just a longer atx board so it could have more pcie ports.

standard and Eatx

since most of useful device are integrated into the motherboard, very few people really needs a standard atx, times when you needed a nic card, scsi/raid card, sound card, internal modem and so on, are over.
in my last upgrade i moved to m-atx and i'm pretty happy with that, i don't really think to sli my gtx460 and with my rampage ii gene i have all what i need in a good looking antec p180 mini, only hardcore gamers needs more

I have a Standard ATX (GA-EP45-UD3R Rev 1.1)

2x Winner for Intel Motherboards Customer Choice Award

Standard ATX - MSI P55-GD65 :)

Standard ATX for me:

MSI P67A-GD55 w/ the beautiful i7-2600k at it's heart. Love it.

I have a standard ATX Gigabyte 790XTA-UD4...

Gigabyte P35-DS4 R2.0 ATX (Intel Xeon X3360) my PC
Supermicro X8DAi E-ATX (2x Intel Xeon X5650) Workstation
Intel D945GCLF mini-ITX (Intel Atom N230) NAS, Firewall
ASRock G41D µATX (Intel Pentium D 820) Office PC
& an old Tyan SSI-CEB (2x AMD Opteron 64) old Workstation, backups

My next PC board will likely be ATX or E-ATX as these are the only "big" form factor motherboards that will fit into the Cooler Master ATCS 840 case without drilling new holes.

I have the Asus Rampage II Gene micro-atx Motherboard i,ve owned this motherboard for a lil over a year now this is my first and probably last Micro-atx motherboard i'll ever buy .there's two things i dislike about it, first iv'e noticed the North bridge gets too hot for my liking and the second thing i realized that if i wanted to add a soundcard i couldn't because i have dual videocards which leaves me no room to add a sound card but then i guess i could always go external sound card but either way it's back to standard ATX only for me if i buy another Mb ;)

I have a standard ATX motherboard that came with this computer I bought at Christmas 07, I'm still running an awful Pentium D too, upgrade time!

ATX, Asus P7p55d (vanilla one!)

I like ATX, I just have a grudge against mATX (had an intel d945gcnl) EATX would be even cooler (not as much bang/buck though)!!! XD

Standard ATX of course. Best bang for the bug and installing hardware to that size is not as troublesome as mATX motherboards. Currently I have an Asus P5Q Pro and so I am behind the curve a bit, but that's fine since this computer can do what I need it to do.

Standard ATX, ASUS M4N78 Pro, and it's a very good overclocker Mobo.

standard ATX i have the EVGA X58 SLI 3

I have a BTX motherboard.... Yeah i know :-(

I have 2 main systems in my house, and one is an ASUS quad AMD ATX system with dual PCIe slots, which is my main computer, and I have an MSI MicroATX AMD dualcore, which sits in my guest room, and is mostly used by my mother when she needs it, or if something happens to my main system, I however, would not mind a VIA PicoITX system for a small cheap HTPC for use on the 46in HDTV we have in our media room.

Standard ATX board because I will never overclock my computer.
ASUS P5Q Deluxe

K8NMF-9 micro-ATX but i OC'd my x2 3800+ from 2,0 to 2,6 GHz so its pretty good ;))

I have a standard ATX-form motherboard... sadly. :(
I want an extended one.

i bet 90% of the people that voted standard atx have a mid tower that is for micro atx mobos and they dont relize that lol.

I've always had a thing for making really small, yet powerful rigs. It's always been my method of building. I don't like overly large computers.

Man ATX form factor has been the standard for A LONG time! Developed by Intel in 1995 and isn't much different that the AT Form Factor berfore it.

BTW, I thought Pico was a modified "BTX" form factor?

Micro-Atx D:

Pico-ITX in my Silverstone FT02

Micro-ATX

HPTX, SR-2 FTW!

I have a standard ATX I think, it's a 2 way SLI ASUS M3N72-D AM2+ that I like alot except where the 24 pin power connector is =/

I've had it a while now and it's still running good.

My main designing computer has a EATX Foxconn motherboard (brand new).
