computer desk 1st build

longjohn · 21 Jun 2013 at 13:33

hi guys im building a computer desk, because its going to be only 600mm x 1100mm but the motherboard tray will only be 300mm depth.

so what im planning to do is raise the motherboard and fit two 120 fans as an exhaust under the motherboard,now would that be a problem, i cant see it being a problem but i thought i would check.

build log to follow

hard to see what it is your trying to do, where are your intakes? what does the airflow look like?

longjohn · 21 Jun 2013 at 13:47

i will have 4 120mm fans as intake at the front and the i would have a raised motherboard the 2 120mm fans as exhaust

Gunda · 21 Jun 2013 at 13:58

If it was me i would have the intakes underneath and the exhaust at the back, keeping the noise of the fans away from the person sitting at the desk.

Also be careful increasing the depth of the desk as a deep desk is not nice to sit at.

SavellM actually ended up moving things around to decrease the depth of his desk.

the problem is its going in a alcove so its difficult to do the exhaust, i was think vents in the desk top but things might get put on them

Maybe mock up something in cardboard to see how your legs would fit under it and arms resting onto etc? Just looks quite thick to me.

its only 200mm high from bottom of motherboard to top of the desk

Put a stove-pipe chimney in the back corner as an exhaust! I reckon it'd look great!

Gunda · 21 Jun 2013 at 16:54

sitting at my desk at work now measuring from tops of my legs to the desk surface = 90mm
If i put some thick books to bring that to 200mm it puts my arms into an uncomfy position that would not be nice "for me" to work at, you might find 200mm no problem at all, just trying to help

i like the input thats why im asking, it gives me something to think about,and im 6ft 2" but i will rework my calculations again

good luck will keep my eyes peeled for updates

now for my hardware

Gigabyte Z77X-UD5H Intel Z77 (Socket 1155) DDR3 Motherboard

Intel Core i5-3570K 3.40GHz (Ivybridge) Socket LGA1155 Processor

Gigabyte GeForce GTX 670 Windforce 3X 2048MB GDDR5 PCI-Express Graphics Card

corsair h100

Corsair Dominator PLATINUM 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz

Samsung 256GB SSD 840 PRO SATA 6Gb/s

Western Digital Caviar Green 1TB SATA 6Gb/s 64MB

Western Digital Caviar Green 2TB SATA 6Gb/s 64MB Cache (WD20EARX) HDD

corsair ax580

BitFenix Spectre PRO 120mm Fan Blue or white LED - Black x5 OR

CF-V12HP Cougar Fan with Hydro-Dynamic Bearing,MTBF300,000hrs and Auto Sensor Control x 5

NZXT CB-LED10-BU 12x Blue LED Sleeve - 1m

i still cant decide wot fans and the setup,as my cpu is cooled by my h100, i was thinking about 4x 120 fans as intake and maybe 1 or 2 120 fans as exhaust.

so my question is would 1x 120mm fan be enough as an exhaust

jonnyp1993 · 24 Jun 2013 at 10:17

I used to have 3 intake and 3 exhaust on my old computer and thy worked like a dream.
Id go for ultra silent fans though as it can get noisey otherwise.

i like to keep a little positive pressure in cases with always 1 more intake than out.

Also with a desk like your building i would think it even more important to have a small amount of positive air pressure stop dust being sucked into any cracks/gaps in the structure. I'd go 3 in, 2 out, or 4 in 3 out.. just make sure you have some form of washable /removable filters on the intakes.

well her goes i have started with the base and working up, as its going in a alcove it has to be small, but i wanted to do something different

so i started with the frame work

always safety 1st coz im always getting wood dust in the eyes

its getting there after some hard work with a file coz my sander packed up, so off to get a new one tomorrow

jonnyp1993 · 28 Jun 2013 at 10:21

Wouldnt you be best using a routor ?

Can buy them pretty cheap these days

longjohn · 28 Jun 2013 at 11:12

the problem is im disabled and havent got a lot of money, so most of my money is going on the wood for building it

longjohn · 28 Jun 2013 at 12:46

things are looking a lot better now

well time to take it back inside to see how things fit

so now to start on the fan mountings

well back inside again to see how everything fits

Looks good, especially considering you've done the bullnose edging by hand using rasps!!
