ATX vs EATX

[preolt]

Hey OC3D Community,

I am building a new rig that is being put into a smaller form factor case. It is a mini tower that can handle an atx motherboard (Lian Li PC-A05N). I love the case but have yet to choose a mobo for it. I am looking at picking up eVGA's new p67 ftw mobo when it comes out in the next month or so. My only problem is this is an EATX mobo. I have never worked with an EATX mobo before, but from what I understand the only difference between it an a regular ATX is the E

correct me if I am wrong ATX = 12" length x 9.6" width. EATX is 12" length and 10.375" width. The difference between these two being .775" in width with no change in length.

Again I apologize this is my first time working with EATX so bare with me please if this is all common knowledge

The mobo trey in the Lian Li PC-A05N is 14" in length and 10" in width. I am thinking that if I installed an EATX boardI would need to drill new holes for that stand offs, this is not an issue I have modded cases before. The challenge is the over hang of .375". First off would it create major issues to have an over hang? I have room inside of the case to do so but is it a problem, and will I have enough mounting points for it to be secure?

If the answer to these questions is an obvious no then I apologize again for bringing up easy facts and questions. If the case is that it is an issue I could probably drill out the rivets and then get a piece of aluminum and create a new tray. This would not be difficult, just time consuming. I could then put in the new tray and every thing would be hunkydory if I am correct right??

If you guys have any thoughts ideas, etc please let me know

Thanks.

The mounting holes on the FTW are actually ATX so you won't have to drill any new holes for the standoffs or anything. It says EATX but it really isn't; it's just a very slightly extended ATX. Real EATX is 12" by 13". If you want to be sure, compare the EVGA SLI pictures to the FTW pictures--on the SLI the holes are right on the edge, but on the FTW they are located a bit further into the board.

So it looks like your only issue would be the overhang, and I actually think it isn't an issue at all. You might possibly hang over by a couple mm, but I wouldn't worry about it. Just make sure there isn't anything putting pressure down on the edge of the mobo as that could cause it to bend slightly.

But anyway, very nice case, I'm sure it will make a great build

I'm thinking about getting the FTW myself if they do actually release it in the next week or so.

Thanks a lot, I was really hoping this would be the case. I lik the looks of the sli mobo from eVGA but for 20-30 more to be able to get the ftw mobo it seems like a no brainer. I am taking my case apart today to paint it all white or all black interior, I am still deciding... might flip a coin

Before I paint though I am going to drill holes for over all cable control.

Here are some pictures of the same case being used with H2o, first link you might need to go to the first or second post. Notice a large portion of them dont have the best wire routing. I am hoping flipping the psu will help me get more behind the tray.

I really hope eVGA releases their mobos soon for the p67 line up, its been 5 months since the original models hit the market and they are still dragging their feet

If you are ever going to put another card in your rig though I recommend evga.

Hmm .3mm over hang just need to decide if this will bother me (im ocd for sure) It might actually help to hide even more wiring ?
