[SHOWOFF] Pimp up my eGPU (Day1)

[SHOWOFF]

The preliminary testing of eGPU interface works, now is time to build a home/box for it, after looking into my IEEE Lab room (also known as my storage unit), I was debating over whether I should take an old solid P2/P3 ATX case or the el cheapo P4 case or even the heavy as hell AMD K6 AT case.

– P2/P3 case is very solid, it seems to be molded into shape and most of joints are welded together, it is constructed with hard metal, excepted to be steel or hardened alloy or some sort.

– P4 case, you know those el cheapo made in china, frizzy, light and looks like can be press into pancake by just 2 person sitting on it. The internal construct is soft Aluminum; where I can bent easily with my finger, and exterior sliding cover seems to be made from same material as the P2/3 case

– The good old AT case, solid, I mean real solid, it must be steel or something, extremely heavy, and seems to be indestructible

Anyhoo, like most engineer who is building any prototype will decided to go with minim work, easy working material, cheap and also want to get it done fast (in that order + laziness). I went with the P4 case.

P4 Case

Good thing about the P4 case is the entire case is so cheap (pricing and construct), it looks cheap and feels cheap, and it is “Riveted” together without any welding or minim screws (I counted 3 on each side panel, 2 for top, 4 for front panels, total of 12 screws!!!). the case has 40+ rivets, and they can be remove easily with good help of drill; with each drilled rivets I also gain 1 aluminum washer!

Body Parts

The most important part of case is the back support, no one likes the video card flopping around, especially one with such weight in the front

P9170031

12.5” Long

Decided that just in case I would like to get even bigger card, such as Geforce GTX 590, I am making the total clearance for video card to be 12.5”, as you see the 560Ti barely fit under 10”

Progress…. (grinded***, refined box)

After play with the box, it seems to me that the soft aluminum is way too soft and it will deform under pressure, so I decided to add outer casing for reinforcement…

Progress…. (end of Day1)

As you see I use screw to join everything together, this is not ideal as too many loss piece, and a lot of pieces you will never take it apart anyway

*** during the grinding 2x Aluminum debris/dust went into my eyes, I write it off as just dust and if I blink enough it should come out, but….the next morning my eyes hurts like hell, have to went to ER twice to get those 2 pieces removed, and for the next 4 days, I am a half blind man, who also looks like Asian penguin.

!!! Lesson learned: ALWAYS WEAR SAFTEY EQUIPMENT, SAFETY FIRST !!!
